I’m a 23-year-old male involved sexually with my straight best friend, who is 20.

I've had feelings for my friend for quite a while now. I suspect he's aware of my crush, and he often reminds me that he's straight, despite our frequent intimate moments together, like cuddling and deep conversations. Recently, while we were traveling, he started dry humping me in the hotel room, and things escalated from there. However, this only seems to happen in the mornings when we’re waking up and hugging; the rest of the day, we completely avoid mentioning it. He also seems to be actively searching for women to bring back to the hotel, using Tinder and similar apps. It seems to me that he's in the closet and quite afraid to come out, which I completely understand. Being gay can be really challenging. But I'm also feeling uncertain about our situation. How would you handle this?
