What is my husbands Obsession with the "taboo" ? Completely gay? Anger issues?

So advice and mature answers please! My husband is , this I knew upon getting married. I knew he had s'd a d before a couple times and that was kind of y to me. Well for our first couple years of marriage he hadn't explored that side at all. Well, to my knowledge. Then for the last couple years he has started to show interest in it again. On top of being completely obsessed with my "". Like annoyingly its always touched, poked, licked are something first before anything else on my body while we are fooling around. I feel like if I was just a giant that's all he would need. So anyways, he has strongly showed interest again, gay , hooking up with a guy he knows, having a three some with this guy and his "life partner" etc. Well, this never bothered me in spurts, but it seems like deep down inside he wished this was a LoT more often. He doesn't know my uncomfortableness anymore. So I make jokes, about how him and that guy would be hot together, saying things like. Oh you love so and so and you would totally marry him if it went for me. He blushes and doesn't say anything. I'm constantly running little tests just to see how gay he is. I think he is very gay, he says he's 100% . Which is hard to argue because we do have l a LOt..but a part of me thinks he just uses me to get off because he is still a man. But rarely does he go down on me, and I have a pretty little flower, and rarely does he touch my . When we have he will hold one, that's it..really, it feels like he is trying to suppress the gayness or something. When out in public he is constantly checking out other men, rarely do I find him second glancing at a girl, rarely. At first I figure its out of pure respect for me. But not sure anymore. When I do see a pretty girk walk by, I say, ya, you see something you like? With an attitude. Just to see how he reacts...its mostly an angry and highly over exaggerated form of denial. So basically I'm wondering is it possible for him to be just now really starting to become gay versus bi? Sometimes like an azz ill say, dude your totally gay and need to just marry a man, he will giggle and half smile and say nothing. then, other times he wilk get soooo angry, defend defend and defend himself. Sorry for all this, but i feel better venting. Also, he had only ever s'd d before. Then I come to find out in the last couple years he Loves! on himself...also he had told me how kissing a guy would never happen and it grosses him out, to then only find out when he was drunk how he had made.out with a couple.guys.
