Hey I'm sixteen and I am sexually active I've never had a problem during sex or before but recently I've gotten a new beautiful girlfriend and when I try to have sex I can't get an erection once when I did get erect I tried putting on a condom and lost all feeling and wasn't able to have sex this has never happened to me before and I have had sex numerous amount of times with and with out condoms so why is this happening now?

Maybe the condoms are too small? Maybe your bervous around your new girlfriend so you don't want to ruin the relationship with her thinking your bad in bed? Maybe your just tired? Lots of foreplay can cause this problem too... a penis can only have so much attention before it "shuts down".

Condoms are never too small.. My sex ed teacher showed us that a condom could stretch as far as his hand to his elbow.
Other than to be sexually stimulated or to have an erection a lot of it comes from your mental state. Having the right mood and atmosphere really helps as well.

See your doctor.....

Best answer possible. If you're feeling uncomfortable, see your doctor

I think your holding up on a pedastal. As georgeous as she is and as high up you can put her, the one thing is for sure. Just like the girl you had the best sex with already - she is just as worthy, just as horny. Sometimes sex has a dirty tone to it - but that makes it intense. Find her hot spots and make sure she knows yurs - it'll open up. Do it before she comes to that conclusion - that this isn't a sexual thing idea - cause they move on quick.
