<human>: Here's the full story:

I'm 17, been dating my first girlfriend for 3 months. She was my first kiss and i lost my virginity to her. I really like her, sometimes I feel like i love her. She has said she loves me before, I told her we are both really young and probably dont know what love feels like. Anyway, relationship going great. I go on a trip on march break and meet this girl a year older than me. We hit it off, I can't get her out of my head the whole trip and we eventually hook up. Came back and added the girl I met and other people from the trip on facebook, I still love talking to this new girl. She's like no one I've ever met and I can't get her out of my head. 

However, I still really really like my girlfriend. I find that i can still carry on my feelings for both of them in my mind without getting too confused. When i'm with my girlfriend I'm all hers and I have a great time and so does she. When i'm chatting with the new girl I feel exhilarated getting to know this amazing girl who I seem to have a ton in common with. 

So here are my questions to reddit: Am I a terrible douchebag? Do these feelings and behaviour prove that my feelings for my gf are false? Should I break all contact with this new girl or tell my girlfriend I cheated on her and therefore end our relationship? Or is this what it is like being a male?
