I’m a freshman in high school and a boy I like who’s a sophomore has been Snapchatting me for a couple of weeks now. I thought he might like me, too, but last night he asked for pictures of my underwear. I said no because I’m not like that. I’m scared that since I won’t send him pictures, he might not want to talk to me. What should I do? PLEASE HELP!

First off it’s actually illegal for you to send them. You could be arrested for making child pornography. Think I’m kidding? No and here’s two links to prove it.

I hate to be the barer of bad news, but there’s a good chance he will circulate those photos. Happens every day. Boys do this to prove how “manly” they are. It is illegal, but once that photo gets out there you can. not. get. it. back.
How is it going to feel having to look every boy in school in the eye once they have seen you in your underwear? Not good. So don’t give them that power. If he stops talking to you then you really didn’t want him as a boyfriend or friend at all.
TLDR: DON’T
Let’s think about this for a second- instead of focusing on who or who won’t talk to you, do you want to be talking to him? Reverse the roles for a moment- imagine telling him, “Hey, send me one of your deepest darkest secrets” and he refused. Would you cut him out of your life?
The simplest rule is this,
Do not do anything that makes you uncomfortable. That is it.
I agree with anon above me – your comfort comes first. If you don’t feel like you can 100% trust this person, I think it’s best that you don’t give him the photos. He may stop talking to you, but if you feel weird about him asking for underwear shots of you, is that really such a great loss?
