Could he be gay?

Basically about a week ago I met this guy in a bar when I was out with my friends. 2 of my best friends are gay men so we decided to go to a gay bar together. We went to the smoking area and I met this guy who told me he was there with his cousin who is gay but he himself is straight

Anyways we talked that whole night and he genuinely seemed so sweet and nice and we have been speaking for over a week now and he wants to meet up again

But still in the back of my head I have reservations that maybe he could be in the closest. He speaks a lot about his self - care routines and his clothing collection. At times we would be talking about certain actors and he would say things like “he’s really hot” and comments like this. Along with it he was very open minded with my friends who are a gay couple, in a way that I had not seen in my heterosexual male friends before. Just these things along with the fact that I met him in a gay bar and he has been back to that bar with his cousin a few more times just raises my concerns

I don’t know, maybe I’m overthinking it and maybe he’s just a really open minded guy but I just don’t want to get too invested and get my heart broken

Anyone been in a similar situation or am I stressing over nothing? Anyone have any sings I should look out for to get a better idea?

Sorry if this post comes across as rude or homophobic in any way, that’s not what I intended, just wanted others opinions (I’m a straight female incase that wasn’t obvious from my post 🙈)
