I already have emotional intimacy with more than just my significant other. However, that other person has already proven himself to be a bad partner in a few different ways (and I'm not referring to him in bed. Though I don't think he's that good there, eitherSee? That's a good explanation for an intrinsic appeal in sexual exclusivity. She needs emotional intimacy with someone to feel comfortable having sexual intimacy, therefore, she will probably stick to one partner. What if you get emotional intimacy with two people? Are you going to fuck them both?
To answer your question, though, I would say no. When I become close to someone, I am incredibly loyal. I may flirt hard, but I simply cannot betray the trust of my significant other.
(The one time I did, I simply kissed another guy, then flipped out and called my bf right away, crying and upset. Yeah, I don't think it's going to happen again.)
