i'm fairly sure girls in Iran don't suck, but then again, they have no homosexuals either, none, not a one, incredible.
Actually i'd be pretty certain if you asked the pope he would say that Mary definitely does not suck cock, and hence the swallowing question is redundant. (actaully she's blown me)
But a serious response, we are a species some 1,000,000-100,000 years old. We have managed to stay viable through lots of disasters and stuff and generally i find that if most men or most women woman innately want something, in this instance its lips around a cock, nature tends to balance the need with a counter need like a woman wanting/needing to suck cock. Likewise for cum, there have to be neural networks, burnt in, from God knows when in our evolutionary past and we fit together, us crazy misfit humans.
I mean can you imagine the chaos if men had a overarching need urge to fuck mouth daily and there was no such counter need/response in women, i think we probably wouldn't have lasted as long, cooperative race we are notwithstanding.
FUCK THIS IS A LONG NOTE!!
