I'm 20 right, and good with girls, but the problem is even with all the sexual desire, I can't physically be with a girl because I'm unable to perform. I can have a totally beautiful naked girl in front of me, even on top of me, and nothing. I'm unable to have sex and this is becoming a real problem for me, I can't even masturbate (I can climax, but it remains soft). The girl usually acts understanding, but dissapointed because she gets all worked up and I can't. I've never had a real girlfriend before, just hookups. I don't even know if the problem is physical or mental. My father whom I live with says that it's impossible for a 20 year old to have ED. What should I do? Maybe find a girl who isn't all about the sex and allow a real connection to form, take medication, or maybe both. My buddy just doesn't want to cooperate anymore.
