Am I normal

Does anyone else have immoral thoughts. I'm in a concrete relationship and wouldn't change that for anything, but there are times when I just want to talk to a female, flirt a little bit.

I would like to think it's because I just want to feel loved, because there are times that I don't feel anything like that. It just makes me feel good to know someone else is interested.

Am I the only one??? Or is this normal or what? I never want a sexual relationship with anyone except my girl, it's really hard to explain I guess. It drives me nuts and makes me feel guilty...
