My boyfriend and I have been together for a year and a half now. When we started dating he had some facial hair but it was shorter. Now it’s grown out down to his collar bone and is very scraggly. I’ve asked him to shave it. And I know men love their beards so I understand it’s a big question to ask. I told him he doesn't have to take the whole thing off, just a trim or if he could have it back to the shorter length it was when we started dating that’d be perfect too. He’s said “oh maybe but just let me look like a homeless person”. And we both laugh about it. But he hasn’t actually agreed to shaving it. I’ve asked him again and he’s gotten irritated by the question now so I’ve stopped asking. His beard kinda grosses me out cuz food gets stuck in it and it gets in my mouth whenever we kiss and then sometimes the shedding beard hair gets in my mouth too and I have to pull it out. I’ve told him this but he still won’t shave it. Any suggestions on how to approach the topic with him again?
