Why do men like cumming on a woman's face or chest?

We, my two friends and I were shooting the breeze. Enjoying the beautiful weather and catching up with our lives. One friend, Rosie, was talking about the prior night that she and her "fuck buddy" were having sex without protection. Then she says "he pulled out and shot his load on her face or chest. She looks at both Gabby and I and asks "why do men do this? Gabby pondered the same question but men don't seem to give a straight answer.

I tried to explain that it is a fantasy to them. They probably saw it in a porn movie and the women seem to be turned on having this done. I asked a few men and one said it's empowerment. Personal experience, I have not had a man cum on my face because I find it messy and sticky. Although I have had one man cum on my chest, tit fuck my breasts and then stick his cock in my mouth as I sucked him dry.
