Weird title, I know, but I was curious if people, lovers in particular, when one is on top of the other, if they could suffocate? This question came to mind when I saw a lot of different sex positions while surfing through Google. I'm asking in compliance with the common Missionary sex position. If they're on top of you like that, all close, do you suffocate? I mean, being close like that, bodies all pressed up against each other, does that constrict air flow or is it kind of like common sense to not be so close because it's risky to do that?
