Is He Gay Or Bisexual

My husband much prefers to fuck my asshole, than he does my pussy.
In fact when he goes down on me, he'll spend more time eating out my ass and sticking his tongue right in there. And only briefly pays attention to my quim.
I'm beginning to think he might be bisexual he's that engrossed with my rear hole. I'd even say he's obsessed with my rear rose bud.
Don't get me wrong I love it up the ass, but I also enjoy being fucked in my pussy too.
If I had to guess, I'd say it's around eighty-twenty in favor of him taking me anally.
