i am 21M, never had sex before, i regret a lot that i didn't have sexual experience in my early teenage, the thing is now i don't that sex drive or libido when i was 12-13, when i was very i got rock hard by just seeing girls knees, that does not happens to me now, when i was 9 i kissed a 12 year old and that was the most powerful feeling i have ever had, that time a thought sex is a thing only rarest people on the world could achieve, and now it is pretty normal and i don't get erection even seeing a girl in bikini
