Is it normal to hit on potential gay/bi guys to draw them out of hiding?

I consider myself bisexual, but I haven't really told this to anybody in my general circle. What happened is that I went on a trip with some friends and ended up sharing a hotel room with some guys. One of the guys, who was actually a friend of a friend, seemed sort of off and kind of weird around me, but I didn't think much about it until we woke up the next day. The other guests in our room were gone, and he kept looking at me. He dropped his underpants to show me his dong, and it was a really nice dong, actually, though I wasn't sure if he was just joking or if he seriously wanted me to do something with it. When I asked him what he wanted, he merely said "You know," and left it at that. At first I tried to simply reject his 'advances' until he became more aggressive about his apparent overtures. Eventually, I decided to bite the bullet and reached for his cock. He slapped me across the face, shoved me off the bed and said "I fucking knew! I knew it! You fucking queer piece of shit!" I was stunned and didn't get off the floor, and he slammed his palm on the counter and starting emptying things out of my bag before he threw it in the toilet and tried to flush. He avoided my for the rest of the trip, but every time I saw him, he was staring at me. is it normal to try and draw gay people out of hiding like this? I'm asking because I've actually been hit on twice by guys who flip their shit and Hulk out when I return the favor.
