how do I know if my friends are gay

Theyre both interested in girls one has a gf sort of. I'll define them as A & B
A- He grabbed me by my waist with two hands, he commented on how feminine and small it was when we were alone in my room.While I was laying down on my bed he looked at me and said wow. I was like what?
He said if only you could see yourself now in an amazed way. I just ignored it.

Another time that made me question his sexuality was when we went swimming.
After swimming we were in the showers and I came out [with my towel on] He grabbed my chest
although I had little to no meat at all he said wow it's soft like a breast. I told his somewhat gf and she was more than glad that happened.I later found out she was into yaoi.

B- He has an interest in asian girls [the ones that look like korean idols]He's still chasing a girl but he also regularly sits beside me and touches my thigh sexually or grabs my ass.
I just take it as playful fun but I started to question his sexuality once he started calling me babe or baby in real life or texts.
