Just wanted to know, since I know someone who really wants to do it with me. Since my biggest issue is PIED, would the sexual act set me back to the beginning or would I be ok?
If you are masturbating to pornography then you are escaping from reality. Using porn as a substitute for real intimate contact with another person. If porn is causing your ED, like with me, then if you are able to have successful sex with a real person then that would be a milestone. For me, the key is to stop using porn as a way to escape and avoid human contact, and start focusing on real sexual intimacy. Everyone is different, but from my standpoint having sex with a real person is far different from masturbation over pornography. There are some opinions that say it could even help your reboot. You will have to determine if you can actually have sex and overcome your ED, then determine if that act has a negative impact on your reboot. The worst case is if you try, and it does set you back, you just get up and start again!
