Am I really a wh*re? Help...

To celebrate the New Year, my best friends (F, L, D) and I decided to have a sleepover at Ds. Her 2 cousins were there, with one other friend and we had a great time. Later on F and I left to go to a park where this boy friend would be waiting for us, just to catch up. That boy and I knew eachother for 2 years, just like I knew my best friends. But there were some issues and we stopped talking until a month ago where he messaged me. We got along great, we laughed so much when we were together and we even made out a few times. Now I talked to that boy and we both agreed that it was more of a hook up, or something like Fwb for now. Because we both weren't ready for a relationship and we just needed some stress relief stuff. But I did still kind of liked him. Of course he didn't knew that. And because we were nothing serious we were still free, he talked to other girls etc. I talked with F, I told her how I kind of like him but that we weren't in the 'talking' zone. When we were at the park, we talked and there were some of our other friends. Before F and I left the guy kissed me goodbye. We got back to our friends house and two other guys came (FF & A). FF and I got along great, I was teasing him, pissing him off but it seemed as if he enjoyed it too. We just kept laughing together and annoying eachother. It got really late so we all layed down on the couch and I ended up laying next to FF. The girls and I were playing Wii while the guys weren't. Through the whole game FF and I were talking, discussing about buying new phones and other stupid things. But with every minute it seemed as if he was getting closer to me and he ended up cuddling me. A few hours later FF and A ended up leaving, but before they left FF kissed me. And right after that F sat me down and kept asking me a bunch of questions. Something like 'What about the other guy? Aren't you two talking? You said you loved him. You're acting like a wh*re.' etc and others agreed on everything she said... And I felt hurt. Because F knew the whole thing, I never told her that I love him, I explained to her the whole situation at the end but she still called me a wh*re. I'm confused, how am I a wh*re if the guy and I were doing the same thing? Is he not a wh*re because he is a male? This situation happened before, but in the past I would hook up with just one guy and she would call me a wh*re. I don't know what to do, I'm just really hurt.
