**** how you sound...
do it look you would do anything else (order a happy meal, talk to a sex therapist)...NATURALLY
You wouldn't order a happy meal like you were talking to your sex therapist. "Oh, i'm feeling a little tired from my long sex session last night. I think a happy meal would stimulate my penis. Don't you."
Stop thinking about what other people think, and start thinking about what you think about yourself. If you can man up and ask her out somewhere or get her number, you've gotten closer to becoming an alpha or a man. If you worry about coming off as some stalking son of a teletubby, you'll try to find the best words and plan all the little ****ty details out. Then one of two things will happen. One, you'll do it but sound like a complete weirdo. (Happened to me once) Two, you'll never do it at all.
Go up to her.
Say hi. I'm carreyreincarnate1.
Use a line if you would like, but honestly if you do, don't use something queer.
Then ask if she would liket o hang out this weekend. Make sure you're free first. Then you know the rest.
*Dont ask if she wants to hang out SOMETIME. It's vague. It leaves much to the unknown.
