Look if there's ANYTHING in the bedroom that you don't want to do, you are under no obligation to do it. I don't know where y'all live where you're surrounded by a sea of couples that require bi play but that's not my experience at all. MAYBE one in 20 couples ask for that sort of thing in my experience and I haven't met anyone that tried to ******* it on the unwilling. All that happened was they asked, I said no and we both moved on because we weren't a match, no hard feelings, plenty of fish and all that. But again it's definitely a small minority and not even in the top 5 reasons of why I don't match a with couples I meet/message.
Really the most I encounter it is on THIS site, and 99% of it is from nonverified accounts who I assume are all desperate horny white dudes with a fantasy who either don't have a woman at all or the one they have doesn't know or doesn't want to participate. It's a huge reason I stay out of the general discussion forum for the most part. I would not take that as a representative sample size of the IR swing world and I would not make any judgements based on the depraved thoughts of desperate, horny, creepy white dudes. I know there seems to be a lot of them and they like ruining everyone else's experience online (not just in this space btw) but it's best to just ignore them until some glorious genius finds a way to identify and quarantine them from polite internet society.
Having said all that, there's nothing wrong with being gay or bi and I'm sure there are black guys more than willing to fill that niche,
I just won't be one of them. But I really don't feel the need to yuck other people's yum and don't understand y'all need to hate on people you're not attracted to for doing things that don't affect you.
@superdick33 your profile says Tampa, I know for a fact there are PLENTY of straight couples around BEGGING for BBC where you don't need to even think about fucking with the nonstraight crowd.
