I got hit with this by a potential plate who admitted she's down for Fwb, fuck buddies and not opposed to me being nonexclusive. However, she asked why I would want to.

This seems like an easy question but the only answer I can think of is "why not?" which I don't like.

I know the real reasons from reading other posts on spinning plates (validity, higher smv, easier to next if needed, etc.) But I cannot for the life of me think of a reason to give to her.

I'll be going active duty in October and leaving the state. I use it as a good reason to avoid an LTR, but she's not interested in that so I don't see it as relevant in this case.

I appreciate any suggestions.
