Do you do this intentionally and if so why?

Meter on the most important element of the scene.
A last question is why are you using an aperture of f/2?

First of all, looking at the negs I see a lot of bleed between frames and the rebated edge on the overexposed frames. To me that says that if you changed nothing between the good shots and you see this overexposed result, you have a camera failure. Looks to me like the shutter is sticking or the aperture is sticking. Look into the lens from the front and the back with a magnifying glass and see if there is oil on either the aperture blades or the shutter blades. Most probably the shutter is causing the problem.
Secondly, take the camera and open the back or remove the back and aim the camera at a table lamp or some light source (illuminated white wall) and run twenty to forty exposures. Look into the back of the camera and get some sense of the amount of light you are seeing and then run the exposures. You will be able to see a much brighter 'flash' if you have a sticking shutter or the aperture blades are not closing. Between the lens shutters are extremely vulnerable to the slightest bit of oil. If the camera were left, for example, in a hot car during the summer months, the oils/grease will migrate from the focusing helicoid into the shutter blade/aperture blades. If it is not a migrating lube problem, then I would suspect a failure in the electronics.
Be sure when peering through the back of the camera to try all exposure modes including manual to see if the auto modes may be failing. Hopefully, this way you will be able to isolate the reason for the heavily overexposed frames. Also, try and duplicate the shooting situations you encounter by running the open back test outside. It is more difficult to evaluate in bright sunlight since your pupils will be closed but with that much overexposure you certainly will see a difference. Try different apertures, such as 16, and run a batch of dummy exposures. F16 will be obvious when you look through the back. If it fails to close down, you will see it immediately.
Lastly, doing the open back exercise may help if it is a camera that hasn't been used much. I typically will run a 100 open back exposures at all apertures and all shutter speeds with a new(used) camera just to exercise because most cameras I buy are likely to have been sitting in the closet and not used for a while.
It is definitely an exposure problem with the camera. Now it's up to you to find the issue! Good luck!

Don't give up! It does get better. I think that your problems are not darkroom related, rather overexposure or camera problems.

I leave the digital work for the urologists and proctologists.
It is pretty much impossible for individual frames on a single roll of film to develop to different densities. Your problem is with your exposure, not developing.
That's just, like, my opinion, man...
These older cameras just go buggy some times. I processed 8 rolls of 120 tonight which I shot last weekend on my trusty RZ (never had a problem) and about half the frames were wildly underexposed, just the opposite of what you experienced. There's almost nothing there. I'm seriously pissed right now, as I spent a total of four hours in the car to shoot these 8 rolls!
Stick with the camera that is working, and keep your eye on it, as it's liable to STOP working. :-)

Do you know how many rolls of film I f***ed up when I started? Calculators don't count that high!
I agree! Pick one camera, one film, one set of chemistry and use one method of using it all. Don't change anything unless you have to. (To solve a problem or correct a mistake.) Do everything the same way every time. Do it until you can do it with your eyes shut.

I know it's discouraging when mistakes keep happening but this is the time to keep going, not the time to quit. The frustration is part of the learning process. Stop now and you won't learn anything. Everything you have done will be for nothing. In business, that's what's called a "sunk cost."
Keep it up! You'll get the hang of it!
As Thomas Edison said, "I have not failed. I have just found 1,000 ways that don't work."
Ok, sorry for the delay in response. Lots to respond to, I'll try to respond to everything as best I can.
Also, before I begin, I also really want to thank all of you for your help. Your knowledge and help has been invaluable to me. I'm sorry I don't really reciprocate because compared to you guys, I really am not that knowledgeable or experienced in film photography.
I admit I haven't looked closely, but the negs appear fine. I don't get prints, just dev+cut. Too expensive to pay for prints each time. I do get a little index card, though as a proof for before I do any scanning. And when I do scan, there isn't any real issue I've found. Just like I haven't had issue with previous B&W rolls.

The Hexar has really liberated me and allowed me to get more shots that are great than I would've with the F90. I just can't see myself going back to that. It is the perfect street cam.
The only thing I can think of is there is an Olympus Stylus Epic (Mju I believe outside of North America) that I can get my hands on for $30. I've heard it's good for street photography, though I don't know how loud it is. Maybe I can snatch that up while I figure out the Hexar. I was thinking of getting it anyways for stuff through windows, as the Hexar doesn't really focus through windows well 95% of the time.
Yes, intentionally. Because it is what I always did on my Nikons. Not officially. I mean, through manual exposure, I'd always have it so the meter was a few bars to the right on the TTL meter. I find otherwise the photos tend to be too bright or flat. It's just a personal preference.

I'm not really using an aperture of f/2. I only use that when it isn't light enough. The Hexar works like this. You set the dial to the max aperture to use. The camera will override that if it maxes out at the 1/250th shutter and will go for a smaller aperture. Which happens all the time outdoors. I don't think I've ever shot wide open outside with the Hexar. Those photos all most have used at least f/8, up to f/22. That's why most of them don't have shallow DOF. The one of the kissing I don't know - but it could lead me to the issues some have mentioned - sticky shutter/aperture blades.
I will definitely try this. But not right now, I'm midway through some HP5. For now, I will try the earlier suggestion of shooting at f/2 then f/8 and see if anything is wonky on the processed neg.

The earlier notation about accidentally covering the exposure sensor could actually be true. I will be more conscious of that now that I checked the manual and know exactly where it is. It is really easy for one's finger to slip.
To the rest of you who said encouraging words and to not give up, thank you. I really appreciate it.
No one answered your question about camera cleaning. I would suggest you find a good camera repair shop to do this for you. You want them to do a CLA - Clean, Lubricate and Adjust. They should be able to tell you if you have problems in the shutter or aperture mechanisms, and they should be able to determine if the meter/auto exposure system is up to snuff.
This should not be horrendously expensive. But unless you moonlight as a watchmaker, you probably don't want to tackle doing it yourself.
Yes, thank you. I forgot to mention that. And now I know what CLA stands for, I always was meaning to look that one up. It sounds like a simple procedure...I know I won't be able to know until I go to a repair shop ... or a camera shop that is affiliated with one (this is what I did when I had my issues way back with the F80)...but any rough ideas? Under $200? Under $100?
I'm newish to home processing as well (3-4 yrs?). I've had difficulties too.
My experience is home processing of film is a necessary step that needs to be completed in order to permit the creativity that is wet printing. Lab processing seems to produce consistantly average results while my own processing seems to produce generaly good but occaisionaly catastrophic results. (fixer before developer anyone? at least i'm in the 99%...). Add the astonishing lattitude created by film processing combined with printing exposures/grade/burn/dodge/different papers/developers/processes etc etc and I'd say you're considering giving up before you've even started on the fun part!
Seriously, that scan and gimp/photoshop editing is frustrating, limiting and ulitmatly unrewarding. I only do that for a very occaisonal colour roll to fuflfill specific requests that I'm unable to decline (family...).
B.T.W my most recent RF CLA (yashica electro 35) was $AU150. But aussie wages/labour costs are very high.
