Gay friend acting weird?

So I met this boy in a theater company we were in together. We have now become best friends and we could pretty much talk about anything together. I’ve known he was gay since we met but now he’s acting weird. Whenever we talk about our fantasies, he usually talks about how he wants guys to sleep with him Etc. But he’s started acting weird. It started off with him saying I was “thick” “hot” and “smexy.” I didn’t think anything of this. Then he started saying he would screw me (have sex with me) even though he is gay and that I would be an “exception.” I thought this was a joke so again I didn’t take it too serious I just laughed. But recently he’s been saying things like:

•(When talking about how much I like my crush) “Well I’m gonna change that.”

•(While he’s procrastinating on homework)”Force me to do my homework”(in sexual voice)

•He guessed how I would master bate and what I would sound like when master bating

•He asked if he could eat me out multiple times and said, “Trust me (my name), I know some tricks for eating out girls.”

•He said he wants to 69 with me

•He moans in front of me all the time when thinking about guys he likes

This is all so confusing because when we are talking about fantasies, he’ll talk about how he wants to eat me out. And then literally two seconds later y’all about how hot guys are and how he can’t see himself having sex with a girl. I don’t know what to think anymore. I can’t tell if he’s joking cause he seems serious. Please help?
