<human>: I've been in plenty of medium term relationships (1 to 2 years). Many of them have ended mutually and others not so well, which I guess if normal. I met my current GF [30 F] at a job I was working last year and we clicked almost instantly. She is Cuban and I am American so things we spicy to say the least. We are definitely in love. The sex is amazing and we understand each other perfectly the majority of the time. She is the sweetest and most hard working woman I have ever met. She never ceases to amaze me even when she fears failure. Despite all of this I think there is a problem with me.

This if very difficult for me to explain so, I will try my best.

I want more sex. From different women. Frequently. It's like an itch I can't scratch. I'm always very curious about what is out there and a pit in my stomach tells me that these feelings are VERY wrong. 

These urges are so strong I start feeling uncomfortable with myself because, I feel like I'm a bad person for something I cannot help but feel. I fantasize about having sex with no one in particular however, even just the slightest thought of someone else's body other than hers and I feeling feverish.

I want to stress to you ladies and gentlemen that I have not cheated in my relationship but, I also wnat to stress that I don't feel immune to it either.

What is wrong with me? Why am I feeling this way? Is there something wrong with me or the relationship?

Can you condense the text into a few key points?
<bot>: M [22M] with GF [30F] for a year. I want sex from other women but, I'm not sure that the way I feel is right.
