Boys are idiots

Ok so there are this guy I'm talking to is so nice and he's a very sweet boy in school but I started talking to him and then he some how turned into a bad boy and the he sent me a inappropriate pic that I wasn't to mad about but I didn't know what to do because I think he expected me to send something to but I didn't feel comfortable for multiple reasons. 1. I've been threw this and it wrecked my life. 2. I want this to be a actual relationship. 3. I don't feel good about my body and because I haven't um shaved down there because I'm not sure if it's right because it being there can help protect from infections but if I don't i won't feel better anout myself but I'm also afraid my parents might find it. HEEEEELLLLLLPPPPP
