Can even mild depression completely disable my ability to maintain an erection?
The trouble with this is that the worse you feel about it, the less likely you will be to have an erection and keep it, even if there’s nothing else effecting you. I definitely get why it’s a downer, but try to view it as a challenge to your creativity rather than your body. There are lots of ways to get her off and by proxy turn yourself on that don’t require an erection…and the sooner you wrap yourself up in those things, the sooner I think your ability will return. Erections by nature are not long-lived, but if you are thinking about other things, that can be disastrous. There are some SSRIs out there that don’t have sexual side effects. You might try getting on one of those. Prozac and Effexor are two I’ve read about that don’t have many reported sexual side effects, and my father has been on Effexor for several years with no functional issues that he’s mentioned. (He’s the kind of guy that gives me too much information, creepy, but at the very least, it might help you, right?
