Is my boyfriend gay/bi?

It's very hard to say if he is or not. I knew a guy who would do things, such as send pictures or ever videos to a gay guy but he is completely straight. It's like a kind of kindness or something. But seeing that this guy is with you, if anything at all he is most likely bi-ual. Just ask him, and if he is okay with his uality he will tell you. Coming out is VERY VERY hard to do. So maybe he hasn't come out yet. But you will never know till you ask.
