I'm 28yrs old and have been having difficulty when it comes to sex. I have been unable to maintain an erection during intercourse. I can achieve one q?

Erectile dysfunction. If you get good erections spontaneously, then it is not likely an anatomic problem. This may be due to anxiety. Do your best to try and get comfortable, and stay focused and interested. If you are worried, worried, worried about how it is going to go, you are likely to have difficult performing.
