What's going through a guys head when he stares at a girl?

You DON'T WANT TO KNOW, bbbbuuuuuuttttttttttt since you ask......

1.) Do we want to have sex with her.....

2.) Do we want to get her pregnant?

3.) Does she have big breasts?

4.) Does she have a nice butt?

5.) Is she good in the sack?

6.) Does she have a pretty face?

and the list goes on and on and on.....

All this happens in a split second...............

All the other answers here are pretty spot on......

Oh, and guys like butts. I cannot lie......

Usually means he's interested and may want to date. Most of the time he's thinking "dirty" thoughts and wants to do stuff..... (Awkward) He either thinks you are very attractive or very non attractive but whatever the case he's seem you and noticed you.

We just imagine boobies bouncing up and down repeatedly for 2 hours

After that we start to wonder if she is a nice person or not

He is probably thing "gee, I have to propel my genitic message into the next generation. I bet that girl also wants to propel HER genetic message into the next generation too."

He thinks the girl is either pretty, attractive in some way, or he likes you (last one is if you know him.)

Probably something along the lines of "why hello Aphrodite, can I offer you something to drink?"

He could have a crush on her. Or he could think she's attractive.

Or REALLY unattractive.

He's Checking you out

He`s wondering what she is like in bed.

Usually how she looks naked, and what it would be like to have sex with her.

It also means he likes what he sees, and thinks you are hot.
