Bi possibly?

My husband and I like to try out different things in bed. Not unusual. We’ve talked about threesomes before but we’ve never gone through with it. No big deal. It had me thinking though.. I can find myself sexually attracted to girls and I’d have absolutely no problem having sex with a girl.. BUT there’s not a single situation I could see myself dating a girl or being with a girl. I have zero interest. Maybe it’s because I’m happily married & don’t want to be with anyone else period but it’s had me thinking. Idk if anyone else can relate or not. I’m not sure concerned about labeling it. Just trying to see if anyone else has been sexually attracted to girls without the desire of being with one
