<human>: Can you provide a brief overview of the text?

My girlfriend and I have been dating for over a year now. We get along really well, have a good sex life, and like being around each other. It's both our first real long relationship.

I'm having trouble, though, dealing with my lustful emotions for other women. We both are in graduate school and when I see cute girls that I would have normally talked to when I was single, I have to really restrain myself into not looking or talking to them. A few times, I have failed and talked to a girl, but never asked for her number or on a date.

I should mention that, because this is my first girlfriend, I have really gotten a lot of self-confidence that I've never had and really feel like dating will be no problem for me if I was single again. I've also never really gotten to "sow my oats" as some would call it. 

I've brought this up with her and she actually said she has some of the same feelings, but doesn't want to throw away our great relationship. I feel the same way and we decided to keep dating and not worry about our future too much and take it step by step.

Are these feelings normal in all relationships? I know its ok to be attracted to other people in a relationship, but is there a point where I should be concerned?
<bot>: In a good relationship, but haven't had a lot of experience so I am really curious about dating other women. Wondering if that's a bad sign.
