I need help!!

Ok so I have had problems with relationships since 6 grade. I have been bullied and played by guys because I'm either not pretty enough or I don't have a certain hair color or I'm not in the mold they want me to be in. So I finally found a guy that things I'm beautiful and perfect. We started dating in December and we were so happy but he didn't tell his parents about me and he also didn't hangout with me a lot we only hung out 1 time outside of school. I wasn't happy anymore so I broke it off with him. Then rumors at school started and I got bullied by guys again. I started to miss my ex-bf and he missed me too. So we just got back together a month ago and he's kind of changed in a good way and bad way. We still haven't hung out yet and he still hasn't introduced me to his parents or told his parents about me which is hard for us to hangout. He has become very sexual with me and I don't like that. I love this guy so much but it's hard to make things work and Idk what to do. So I need some of ur girls opinion on what I should do. I feel like if we break up again it's just gonna go back to me being bullied and i don't think I can take it anymore.
