Would it be bad if i sent him a picture..?

It's only slutty if your face isn't showing, meaning it's just a picture of your body. So show your face, and smile! Adding friends in the picture helps too. And remember, don't send it unless you'd be okay with it ending up on Facebook. When people are seeing you in person, at least you know who's seeing. When a picture gets out on the internet, any number of pedophiles or weirdos could be jacking off to your picture in the privacy of their home. In person, you know that's not happening.
