ok so from my early teenage years(13-14) i have been masturbating and at 15 i had sex 3 times altogether with my gf and i lasted forever then we split up and 2 years later without having any sex or gfs inbetween i met a girl started dating and she starts making hints she wanted sex and i knew she had experience so i get to the point where im about to start foreplay with her all goes well (being really nervous of course because i want to be "good" to her standards) i last over an hour unprotected without cumming we decide to stop and again and again we keep having sex every few days i last longer than she actualy bear to keep going eventualy 1 time i cum but after 12 minutes i thought it was abit soon i didnt mind neither did she i was glad to just be able to finish next time we have sex i cum within 3mins and its been the same ever since about 20 ish times having sex im cummin really early and im also cumming early mastubating aswell now i dont know whats going i usualy last forever with masturbation and the first few times i had sex but all of a sudden im cumming to soon plz help i really hope this isnt permanent :S...

yer it does if it isnt left long enough to be able to cum again but its just a pain to do. i get alot more from having the sex without cumming then cum then having the sex
