Husband admitted something

I’m posting anonymously bc I’m kinda embarrassed! My husband tonight while I was giving him a BJ, totally opened up (which I greatly appreciate and have always wanted him to do) and was expressing different fantasies and talking kinky (all fine) but then he kinda hit me with something that’s left me feeling a little weird bc I didn’t expect this from him! After tip toeing around it he finally said he wants me to fu&@ him with a strap-on, and finger his a-hole and basically get as kinky as I want with it. He then expressed how hot he thinks I am and I turn him

On and make him feel comfortable enough to go outside of the box. This is coming from a man who is like the manliest burliest straightest arrow person and now I feel like wait a second...do i REALLY know my husband? I can’t help but let my mind wander asking myself omg is he gay? Is he just wanting to explore? Should I be concerned? I’m more “vanilla” than I thought. Because that request totally weirded me out. Help me

Out, is this normal????????????? I feel so weird!!!
