You know what... I'd be into this sort of relationship interplay if I could physically get jealous. I love it when my SO twists me around her little finger.
Also Kids... in response to all the comments above. Do whatever you like in relationships (with consent when it comes to the sexytimes of course), especially your early ones. It's the only way you learn what your boundaries and standards are.
Some people think 'cheating' is some sort of betrayal of trust. Maybe. But everyone has a different approach to intimacy and the best thing to do is discover your own.
