I liked masturbating, but then I felt really gross about it. What now?

I'm 13 years old. I've had an interest in sex since I was 10. So when I heard about masturbation for women, I was all for it. When I tried it, it felt great. But afterwards, I felt sick to look at my self in the mirror. I was disgusted by what I had done. Whenever I went back to school, I felt like everyone knew what I had done. I know they don't, but it still feels like it....

How can I keep from getting upset when he ignores my no?

I'm 15 and my bf told me about a week ago that he thought I should be loosing my virginity and a few days ago I did. I was ok with this and only said once that if it was ok with him I'd like to stop (the way he was looking at me was creeping me out), but it wasn't ok with him so he kept going....
