How me [21] and my husband [28] are developing our sub journey.

Over the last year our kink has been developing at a rapid rate and we have grown to know and understand each other a lot more. In saying that there has been some revelations that I wasn't sure how to feel about and maybe am still uncertain about, although they're not deal breakers or anything I just can't help but overthink them.

My husband is a super DTE guy and very likeable guy, he despises confrontation and any sort of uncomfortable situations, which means we're always taking the easy way out of real life problems which is fine but I have starting overthinking these things due to our sex life being the way it is and I'm completely fine with it.
Recently we bought ourselves a torso dildo and things have been going great and maybe progressing somewhat quickly. During our journey over the last year I have figured that my husband is bisexual which I don't mind and find kind of hot. I like the idea that we can both be submissive together. However I thought the extent of his actions would go as far as pleasing other men in the form of being humiliated such as being spat on, eating their cum, kissing their feet and he's even talked about rimming them while they fuck me. Since we got this torso dildo I have noticed a lot more acts that go beyond just wanting to be humiliated by men and possibly wanting to be fucked. He loves rubbing the cock over his asshole and closes his eyes which is pretty obvious what he's thinking about because he finished almost 3x like this.

I obviously don't want to overthink this and make any correlation with his normal personality outside of his desires but I was wondering if we should introduce pegging into our lifestyle but I'm honestly scared it's going to make him full gay, I know that might sound ridiculous but you have to understand this is an unknown to me and do not want to anything that might jeopardize our actual life together.
