I've been in a relationship the whole time. It wasn't bad until I took bupropion which destroyed me mentally physically etc but now am making it work. You just have to recognize there is another person, it's not all about you. Sex is mostly for her but it is also for me because it makes me feel a bit more like a person. I try to get out of my head about it. BTW my sexusl dysfunction is extreme right now, not full erections, tight pelvic floor, zero feeling, no libido. But I still have sex. The mental aspect is entirely fixable. Do not focus on the sexual. The sexual side will never ever heal without healing thr cognitive issues first. I did heal after a year but not fully and 1 pill bupropion 'crashed' me to put it lightly. You can build yourself up you can do it. Thought processes are make or break with this condition.
