So like what's yall thoughts on fixed positions in BLs (bottom/top)

Just doing a mini research, trying to find out how many ppl actually want a switch couple vs a fixed one. Cause honestly like comparing gay irl vs bls, not much ppl are switches too. (My fav gay bar did a survey lol with 400 ppl who answered) So it got me curious why do ppl want it so badly?? Won't share my opinion on it rn cus it might affect u answering
