Cheating

I met this boy about 3 months ago and we hit it off great!! He's going to college and told me he didn't want to get into a relationship with me right now bc of bad timing however we're basically bf/gf just without the title. Well, about 3 weeks ago I had sex with another guy and I did it twice it wasn't an accident I knew what I was doing and I know it's wrong but I have no regret. I don't plan on doing it again but idk how to feel. Me and my "bf" aren't official but I still cheated on him. Does it make me a bad person not to feel any remorse
