Have you ever thought about being with another person while you were in a relationship?

I don't fantasize, but I consider my relationships and interactions with different people and think about how they influence my life. I have a lot more to say about this, but I haven't quite worked it out in my head yet. Ultimately, I wouldn't be happy imagining or going through any affair, I only want one man in my life, and as long as both people are contributing to the relationship and each other and still trying to work on themselves, and there is some kind of equilibrium, I see no reason to look for anything more. If that doesn't happen, however, I tend to seek out more intellectual and playful (not sexual) stimulation, in times of overwhelming discontent.

I think it's human nature.

I'm afraid so!! - The secretary where I used to work made it very obvious that she had a thing for me so I used to think about her when I was making love to my girlfriend at the time!!

Yep. I never want to actually go through with it, one frisky lady is enough, I mean I'm not a teenager anymore but I do think about it.

The last time I had a fantasy about another person I was condemned. Like Alicia Keys girl on fire and Taylor Swift wildest dreams

Very common
