Exact same problem here. I wasn't on meds either. What really helped was talking it through with her (about the anxiety) and luckily enough I was with someone understanding enough to listen without judging me. Apparently she had thought the issue was her (so my problems were actually causing her mental distress) and so me telling her this was a load off her mind. It also took a lot of pressure out of the situation, and I ended up being able to climax without first going through an hour of sex! lolusually ended up in us going at it for about an hour and then giving up most of the time lol.
