man i also go this problem,ill tell you waht dont work in my expereince,that desensitizing lotion you can buy stay away from that it actaully makes it harder cuz if you cant feel your penis stimulation doesnt work,if you lose your hard on,and its just not enjoyable to you.And stay away from letting the girl get you going cuz if shes doing stuff to you and your almost ready to come then having sex surely wont work.It is true though after you have sex and wait about 20 min then you can do it all over i actually get tired before im ready lol.other than that i wish i knew more about how to stop it cuz personally i dont notice i last lasnger than the first time i had sex.but can i ask you a question? Are you nervous at all when you begin making out? i think that my prob i get nervous then i spend to much time thinking about my dick and not my girlfriend.Other than that dont know what to say.anyone else have any answers?
