Is it normal for a gay man to have frequent sexret sex with a woman ?

I've been sleeping with an old friend. We've known each other since high school and have always flirted and joked about sex. Last year he confessed to me he was gay, but we continued to discuss sexual situations. In august we were going to a comedy show my friend was hosting, and we ended up meeting up at his house and sleeping together. We have been in a friends with benefits relationship ever since. The worst part for me has been the level of intimacy in the sex. He stares into my eyes and holds my hand and kisses me the entire time--and we go for hours. He also has no issue with giving me oral sex, in fact, i can't stop him.

Is he gay or a confused bisexual? I know he has sex with men so there's no lying going on there, but he makes it seem like he has deep feelings for me (though he's denied this). Normal?
