...Just Can't Resist Sometimes...

I've been with my partner for five years now, and we're pretty happy together. I love him and all, but there's this... something inside me that just can't resist when I find someone new who looks at me like they want to eat me alive. It happened again last week, met a guy at a bar, he was everything that's not my boyfriend, you know? Handsome, confident, single. And then we ended up alone in his apartment... It wasn't even the sex; it was just being with someone who wanted to give me all their attention without any of our relationship baggage hanging over us. But I feel so guilty afterward, knowing how much this would hurt him if he ever found out. It's like part of me wants to stop but another part... well, it'll always come back again somehow.
