nudes (kind of)

So I sent like and inch or two of cleavage and like an inch of the top of one butt cheek to a guy that I thought I really like and he was really into it so I sent some more cleavage and the next thing I knew he sent me a dick pick saying look what you sexiness caused. I'm 15 and I was curious but when it was all said and done I started crying and I feel like a slut. Being a curvier girl it felt nice to be sexy but there's this guy that is so incredible and whenever I'm feeling down he tells me how beautiful and amazing I am one catch he has a girlfriend because he's perf all I could think about is how I wanted it to be him telling me I'm beautiful instead of a guy calling me sexy. Sorry for the length I'm just confused and upset and idk upset.
