I don’t get the bathroom thing either - if we had unisex bathrooms I have a difficult time picturing men and women getting together for sex in those bathrooms - the whole thing is completely bizarre IMHO.
In clubs, heterosexual sex in the bathrooms is common. Obviously no children are around. In a club, you get dressed nice, dance and make out to get with women.
Most women need at least some ‘foreplay’ and a decent setting. Women also care more if you mess around with other women. Men don’t care as much about that stuff so gay guys are perfectly fine “cruising” for multiple partners in any public bathroom 24/7.
If there was a free place to meet multiple women for sex(and not even have to dress up to do it), many men wouldn’t care if it was a public bathroom. But women don’t work that way at all...
