Has anything helped you for sexual function? Especially in males

Hi hello! I've started seeing someone new in the last few months -- he's lovely, but he struggles stay hard/come due to the antidepressant he's taking. I forget which.

I'm glad he takes it -- obviously I'd rather he have this side effect than experience the alternative, but I can't lie, it's not ideal for me. And we're early enough in dating that it may just end up being a dealbreaker, but I'd still like to keep working at it a bit. And really to his credit, he absolutely makes sure I'm satisfied regardless. But ahh yea the whole experience can leave me wanting a bit.

I don't want to talk to him about it directly yet because I feel like that would be a really good way to kill the vibe entirely. At the moment I'm just soft doming him to try and let him fully relax and be present, but I'm wondering if there is anything else I can do? Has anything helped for any of you? Appreciate your insight x
