Fetish: Cumshots into mouth and swallowing - why do men find it such a turn-on?

[vjenka90]

I, myself, am a fan of any porno that ends with a good cumshot into the mouth, especially if they swallow. I can't explain logically to another person why I find it so hot and such a turn-on. If you find it a turn-on, can you guys explain why you find it a turn-on? Imagine explaining it to someone who literally doesn't know the reason we find it so hot.
