dude oh my gosh im in the same boat someone help!

try to forget about getting a boner and just enjoy. All of a sudden, you'll be happy with what you see. Try a little bit of alcohol and some good music before sex. That will keep your mind worry free.

Alcohol?? He's 15!! Come on!!

I do agree though, try relaxing and just letting it happen. It could be just a mental thing, and the more worked up you get about it the harder it will be.

However, if that doesn't help at all, you might want to see your doc, because at your age, you shouldn't have this problem.

Yea, suggesting alcohol to him is not a good idea. Dont try that.
I realized I cant get it up unless i'm not trying to, just let it happen.

well heres my problem ive tried 3 nights in a row and NOTHING!!! i have never had this problem before. ive had pretty good hard ons before but now i cant even get fully erect. they are like semi erect. its gettin me pissed and my girlfriend and i sure dont wanna lose her cuz my guy cant get up.....what can i do????

ohh and im not nervous about it so it cant be that.

i am having the same problem. when i fool around with my girlfiend i can get it up no poblem at all and of course she notices. But once we get our clothes off i just cant keep my boy up. I really wanna have sex with her too and so im trying to get my boy up but once i do hell go down again after tyin to stick it in. one thing is that she doesnt like foreplay all that much she just wants to get down and screw. I am a virgin but she is not, i really luv her and wanna show her that sexually. Please someone give me some advise!!!

im about to be 18 and my girlfriend and i mess around alot...just little things most of the time cause her parents are pretty protective and can barely get any alone time at my house, well while we are doing just little things, i can get it up just fine, almost all the way. but right when we switch off and she starts gettin her hands down there and all that good stuff. well it just doesnt stay very hard. i mean shes not the best at what she does but enough to enjoy it. i guess my problem is that it used to go up just fine and sex used to be a non issue, but this is like the 5th time its happened in a row, and its become somewhat of a bigger issue now. soometimes it just doesnt even go at all =\...anyone got some tips? talkin to the doc is the last thing i wanna do, but i will if ive really got to =\
