[Became kind of a long ramble, but I had to let it out]
Same here with the 13 YO virginity loss and the cringing, I remember I had never even touched myself before or thought about it then some 15yo really cute girl was hitting on me on and on and I just kind of let things happen, lacking any real consciousness of what was going on or where it was going, except that it was sort of exiting but sort of awkward.
Then with other people it would be roughly the same thing for years, I would always find sex kind of awkward no matter who I was with, wether female or male, hot or not, for sex or for romance... and they (my partners) constistently did not find it awkward and would say things like it's ok and come back for more: why everyone was pretty OK (everyone meaning about 15-20ish people total) with it and I, always I and always me, noone else, felt awkward? That was odd, I felt guilty about it and did not want to make my partner feel down by always refusing sex because it was not like there was anything wrong with them, they were not "pressuring" me or forcing for it or anything, I just did not want to let someone I cared about down because of some silly unexplainable "awkwardness" issue I, and always and only me, had in the relationship. So I tried to kind of give in and compromise and just try to be a good partner!
Then after many years I realized I did not feel at all confortable with my male role and body then purposefully decided to stop playing into that, after which everything became much better, even "OK to good" sometimes instead of just "awkward"! Hopefully after I get this "male body" thing fixed, it will be even better. I suspect it will be better in spite of the drop in T and that I am not talking myself into believing into a nice but unrealistic situation. If anyone has had a similar experience about feeling weird first then after HRT and physical changes getting into sex, I'd love to hear about it.
I've seen a few comments going that way and it's been incredibly relieving, I would not want sex to become even more of a turn off after getting low T levels, but making it exiting by just not having male equipment, face, voice, etc. When you manage to get your mind/body into it can feel really great and blow off tons of steam and create connection and intimacy with your partner and all that, I would not want to give it up :l.
Cheers!
