No, but he likes sucking fake dicks, he gets turned on talking about sucking dicks and he is always wanting me to fuck him with my dildo. So, last night I did. He took all of it with no problem.
Seems a lot of guy think about bisexual stuff for a while but avoid it due to social stigma. Maybe its just a fantasy or maybe its something he has done in the past
I think your husband is a ways away from being gay, or at least my definition of it. In my book to be gay you have to love men not just have sex with them. Some men just enjoy the stimulation of a dick in their mouth or ass. It is the activity with the object that they crave, not the emotional connection. If you still enjoy that connection you shouldn't be worried.
