I'm gay, my bf is bisexual, this is his first same-sex relationship though not mine. We've been together for a year and a month and we started flatting together about 6 months ago, (not on our own, mind).

We've had a good sexual relationship to my mind for most of that, his libido has waxed and waned like from fortnight to fortnight which I learned pretty quickly is just the way he works but I was ok with that, I could manage. Lately, I'd say for the last 2 months, he seems to have lost pretty much all interest. We have two beds for convenience (like if one of us is working late or sick or something) and though he didn't always sleep in my bed, lately he's barely at all.

He's pretty much just been using anal and lesbian porn to get himself off and the few times we've had sex recently it's been while he's been particularly wound up from the porn - which he carries on using during.

Emotionally, not much seems to have changed apart from me slowly becomming stressed out. I haven't had to deal with this before. If I try to get amorous he'll resist and be apologetic, so I don't pressure him. When I try to talk to him about this, he gets quite uncomfotable but tries to reassure me this'll pass, but I'm getting more and more concerned either he's lost interest in me or that this is a longer term thing. I'm not sure how much more patient I can be.
<bot>: Boyfriend and I have mostly stopped having sex and I'm worried he's losing interest in me or maybe guys in general. What can I do? Is there anything to do?
