I tried searching but found nothing in this Reddit.

What is the RPW way to deal with a man who has problems with his penis, be it a "size" issue, premature ejaculation erectile dysfunction or impotence?

My best friends are guys and I have that 'thing' about me that gets them to open up about very personal issues. I've also sexually dealt with a man who had issues with his penis. I know that men put a lot of weight on their penis - the size/girth, whether it functions when needed, and sexual prowess in the bedroom. Having it malfunction, as I've seen, is utterly devastating to the man in question.

I know the basics: - don't take it personally - be understanding - look at lifestyle (diet, weight, drugs)

I'm wanting to know how to deal with the man's psychological and emotional aspect of it as a RPW. I'd also love to hear from the men here, if they've had issues and what they would have liked their partner to have done and not have done.

(Edit: Tried to make this look less like a clump of text, but I can't wrap my head around Reddit's formatting.)
