Difficult parents

I am in college, but my parents still try to control who I am. I can't listen to different music without being a "gangster" or one of those "rapper people." My mom thinks just because she never drinks means I won't. They also don't want me to have sex. It's difficult maintaining a relationship with someone when I have to be fake around. Everytime I get home I turn it to a radio station she has preset on my radio. I take alcohol out of my car and hide it and the condoms when she ces to my apartment. I feel like I hide a lot from them, but they'll never understand. I feel like I am alone in this.
