My boyfriend called me a hoe

I'm 16 and I have to admit, I went through a little stage my sophomore year. I wasn't being a hoe, but I kissed one guy, another guy forced me into sex, and another guy sent me nudes. Every time that's brought up my boyfriend calls me a hoe. That happened before we started dating and I've been loyal to him ever since. He cheated on me back in May, a week before my birthday and I took him back because he was fighting for us and I forgave him. But when we argue all he's got to go against me is things that I've done in the past. I learned from my mistakes. It's just really hurtful when he calls me a hoe because he's suppose to make me feel wanted and special and he does the opposite when he calls me that. He apologizes sometimes but others not. I just needed to share this.
