I have been with my gf for a few months. and we have be having sex for awhile now. But sometimes i just can't get it up to have sex. Unless we have sex right away i lose interest. I can't keep it hard. IDK what is. I used to masterbate to porn everyday b4 we started to date. she is the 5th person i have been with. and when we do have sex its good but i dont last all that long. I just dont have a drive for it or i cant really stay interested. at 1st when we 1st start to mess around im ready and into it but i dont stay interested very long. and of course i have to keep her into and keep her wet or make her wet before we can have sex s i cant just jump right tooo haveing sex. any help guys....shes starting to get mad....and i have noticed i can't have sex more than once a day either...Im only 20yrs old and its hard to explain to her its me not her....
