Yeah it was definitely entirely HIS fault it wouldn't stay up. *sarcasm*

You should help him trough

the same thing happened to me the first few times i tried to have sex. i just couldn't keep it up, but just keep trying and it will work eventually, you just need to find the right time and place and make it as comfortable as possible for both of you. A lot of ED is caused not by physical problems, but by your mental state, especially performance related anxiety and ED. In addition, if this doesn't seem to help make sure he isn't watching too much ****, as this really messes with your brain's natural reward system. I know that might not be something you want to bring up, but if he cares enough about you(and he should if you are having sex) he will work to make it happen, and believe me, it will be totally worth the effort.

some guys say they can't get it up so they don't have to ****

just go grab it. take charge. it might work and if it doesn't. chase him around with a carrot and see what happens

Oh please. I had a guy break up with me because of the same issue. I was okay with it but his ego wasn't.

Or to break it to you your not that interesting guys can also get uninterested
