I swear to god my penis doesnt work lol.actually it's not funny but funny in a going crazy kind of way i guess.Ok so heres the down-low,im gonna say all that i think is relevant to my problem. So ok im 21 and very first partner my gf which ive been dating for 4 months now in a few days,everythings all great from her in our relationship,except our sex life.So now i come the sex part of it.when we goto have sex i get very nervous like i can almost shake the bed with my heart,and i get all tingly.Then if we start off slow i always pre-jac before we even do anything like i can be just laying on her in my clothes still???AND even after i do it once well agree to just cuddle for like 20 mins untell i can go again where as it happens all over again,and its not just pre-cum its a wack load.The only time i dont have this problem is when i have a few drinks,but im still so nervous that i cant get it hard fully.can still have sex with her not just fully enjoyable.but i would rather have that then premature ejactulating then i cant get hard at all. Its weird cuz if i would masturbate,i can go for like 20 mins if i go slow,i can control it there also using the stop and go way.So i want to know what is my problem,there has to be something i can do about the ejactulating before anything actually happens,makes me seem like im so horny that as soon as she touches it i cum.i need to overcome this problem.PS ive also tried that desensitizing stuff but i find it hard to get an erection since i have no feeling,so i cant use that.and since im not actually inserted in her i dont think a thicker/stronger condom well help.
