why do I do it?

I think that's a shy little girl talking...lol Don't be so shy. Tell him or everyone for that matter what you REALLY want. If you aren't honest about stuff like that you may let him get away. If you say no...or I don't know he may not ask anymore and then you are just screwed. Just be honest. Pick all the butterflies out of your stomach and just let him know!!

Or you can do what I used to do...and say if you want to.....hahaha
