So I 28m have only recently started having sex, I did for my first time earlier this year since then I've been with two other women and have been with all three of them several times and I just can't finish with any of them.
The first person I was with I thought maybe nerves or frankly some hygiene problems she had were to blame
The second person I wasn't all that attracted to so maybe that was the cause
Now I'm with my current gf there are no hygiene issues to speak of I'm definitely attracted to her but still nothing.
This last weekend we were at a hotel doing our thing and for whatever reason I just asked her to bite the head of my penis, she was a bit hesitant and was gentle at first and I just couldn't feel it at all, she bit down harder and still could just barely feel it and she said it should be hurting, I decided to pinch myself as hard as I could and had her do the same and again almost no sensation at all.
I also find that when we actually have sex at first it feels great but after a few minutes I again just lose all sensation to the point I can't even tell if I still have a boner and I don't really know what to do? She said something along the lines of the head should be as sensitive as my balls are and I'd compare it more to a finger in terms of sensitivity but I'd say less than that still but it's pretty close.
I looked up causes for lack of sensation and one thing I saw was frequent masterbation can be a cause, I'm currently on a 2 month long dry spell with only attempts being with my gf but still the same we've tried a few things, pretty much all the basics other than anal which she just doesn't want to do. I also saw diabetes as a potential cause but I had blood work done back in March and everything came back fine on that, last cause I saw was not being very active but I run almost every day usually at least a 5k up to 15 and occasionally a half marathon I also lift weights regularly so i doubt that too.
I don't have a family doctor so I can't really go see anyone and I don't really know what my next steps should be to address this? Anyone have similar issues?
