He is gay so most likely he is just being friendly, has an obsession with feet, or curiosity is killing his cat and want to experience see what its like doing it with women. I wouldn't hope for a relationship if I was you if you are 100 % sure he is gay.
Then Yes he wants to be more then friends as people don't just do that normally. Or he has an obsession with feet. Have you seen him do that to other people or heard someone talk that he does?
