Actually I would request the same behavior from both groups. Both activites should be enjoyed privately where it won't disturb others. If I check into a hotel room I have no idea if someone has had any sex in it of any sort - gay or straight. But you know if a smoker has been in the room. The same goes for cars, airplanes, trains ect.

Go walk out on the street and look at the curb. See any sex there? No. See a bunch of butts? Sure you do. Understand now?
