losing social status?

no
It's only 3 months into school and I lost some of my friends. They let me go because I'm very sexual and I put it on snapchat and they saw it. It wasn't nudes but I put some inappropriate things up. The point of this is that they ignore me and don't want to talk to me anymore. One girl in my class that sits next to me doesn't want to look at me or be near me because of that. When I was having a lollipop in my class the whole class stared at me and said that I'm sucking it like its a penis. Like how's the right way to eat candy? And some were telling me to chill with that. 
Are they right to say this or not? Just because I'm sexual doesn't mean I'm different. They should know that one day they'll have sex or make sexual jokes or be provocative and they get mad at me. Should I change myself or stay the same?
