I am suffering from sexual performance anxiety which is causing me to loose my erections just before or in between sexually activity. It is nervousness of having sex. It is embarrassing and I am not able to get over it causing me to think of it and feeling guilty. I am pretty sure that I am not suffering from erectile dysfunction as such a thing does not happen to me when i'm masturbating. But every time i'm about to have a sexual activity, I think too much and it kills my erection and sex desire. Please help.
