I've always found it hard to stay completely faithful in the past. I don't know if it was biology or raging hormones, but that's why I'm not married yet. Marriage is a monogamous institution, and I think if you enter into it then you have to play by the rules. (And yes, that includes the bachelor/ette party.

) But you don't
have to be monogamous if you don't feel it's right for you...just be up-front and honest about it. Nothing wrong with that. It's a personal thing...now that I've met someone I'm willing to be monogamous for, I don't find it hard. But it
is difficult to not be monogamous when the whole world is telling you that you need to be.
Edited to add: I think it's totally normal to be attracted to other people while you are in a monogamous relationship. However, I'm like the girl in the article...what I really care about is how my partner
feels. I would be more crushed if he didn't care about me than if he just kissed someone to satisfy a curiosity.
