What does it mean

OK so this girl I know, who happens to be pregnant, just sent me a picture of some guys huge cock today. No explanation or anything. We have traded our own pics in the past but I'm not gay at all. So any ideas why she sent it or what I should say?

I'm guessing she's making a comparison, and rubbing your nose in it a little, letting you know you just don't measure up to her expectations.

Well I'm pretty big but yes they where bigger. I asked a friend of mine what she thought about it and she didn't answer me, just wanted to see the pics.

She might cocktease you, she thinks you'd love that cock in your mouth

Options:
-it was a mistake, meant for someone else.
-she is trying to tell you she is extra horny from being pregnant and wants you to fuck her.
