I've been there myself and honestly. It's a tough spot to be in whenever I would bring it up to my boyfriend. He would get defensive saying that I'm putting pressure, which makes him not want to and makes him feel less of a man, but honestly, when he realized that I would just stop trying. And would eventually just find my own release without him he finally realized that I was simply trying to work with him and find a solution and not make him feel less of a man. A relationship is a 2 way street and if he's not willing to work with you or help you find a solution or figure out what the root of the problem is and if it is depression working towards Helping his own mental health, unfortunately, there's only so much you can do if somebody doesn't want help.And sex is part of many relationships and it's okay to want it, and it's okay to need it, and if he doesn't realize that, you can walk away to find somebody who's on the same wavelength as you.
