I am fit and healthy, and take good care of my body (don’t smoke/do drugs, play sport frequently, etc) and have a stable girlfriend.
Whenever we are in the mood and i begin to put a condom on though, my erection goes. I have had blowjobs and handjobs from her before and performed well, but when it comes to sex, it doesn’t work.
Is it erectile dysfunction? If not, what should i do?
