@AlteredEgo nailed it with her first post in this thread (no pun intended).
I realise that the original poster asked only for female responses, but as this is an olllld-as-fuck thread anyway... I wanted to weigh in on the PE issue, since I really feel a male's perspective is actually more helpful on this specific issue, and someone else might Google this in the future:
Ladies, do not let your guys get interested in PE. There is never an occasion where it's necessary. If his penis is so teensy-tiny that sex with him is genuinely of insufficient enjoyment (we're talking borderline micropenis territory), then the 'gains' that he
might make will be so negligible that it wouldn't be worth the risk of injuring himself. Try to convince him to be sensible. If you have less meat and skin to work with to start off, then there is just not much you can do to change that. You only get given one penis, and if you stress it with weights or start doing strange exercises, or pumping it in a fucking vacuum -- and something goes wrong -- you don't get given another one.
To the guy who resurrected this thread to talk about his ED -- have you tried taking L-Argenine supplements daily? Losing weight? Changing your diet? You may feel that you have tried all of the usual suggestions already, so forgive me if this seems condescending. You have my sympathy, although I'd suggest that the girls above have it correct once again that diabetes is generally a manageable condition, for most people, unless there are other medical issues in play.
