I'm only 19 years old, I haven't had sex yet, I have a girlfriend but we still haven't had sex. The problem is that I have low confidence about having sex with my gf because I can't get full 100% erected while passionate kissing and touching. The touching is clothed. Not that I'm not hard at all, I'm hard let's say 70-80%. I'm sure the problem is not her because she is very attractive and sexy to me and i love her very much. I don't know if the problem is with me, I don't know if I have a reason to be worried, maybe the problem is that we are not naked while touching, or becasue she doesn't touch my penis (she's not so comfortable still). I don't get fully erected even when I watch porn,,only 70-80%... sometimes I get harder but if I don't keep masturbating it goes away a bit.... I'm worried
Your problem is that you're worrying too much. Try to relax. The first few times being sexual, nothing happens the way you expect it to. You have to understand that. Just relax and go with it, you'll get the hang of it. If after a few attempts of intercourse you still can't maintain an errection, then you might want to talk to a doctor.
99% of sexual arousal is mental. When you're on your own, whether it be with porn or not, you know that the most intimate sexual activity you're going to achieve is masturbation, so your brain knows that a full erection probably isn't really necessary. When just kissing & cuddling, it's much the same. However, once you're put in the situation where actual sex is imminent, the chances are that not only will it be a full erection, but so much so it could well be bordering on being painful due to it being so hard.
i dont think its mental...your dick either gets hard on cue or it doesnt....dude coud have a clogged valve somewhere...getting partially hard is a physical problem op-do not take chances with your penis...go to a doctor...you dont rule out mental first...you end up at ''mental'' once every physical avenue has been checked
You need to relax, stop focusing on the tool, and concentrate on the act and on your partner. It takes some exercise but it can be done, and the rest naturally follows. You can use some magic pills for the first few times. It helps me a lot.
