It's hard to juggle like that, and I am a one woman man anyway but it was hard for me, when two of them had the SAME FIRST NAME and when one called I did not know how to identify which one was calling.

But to answer directly the question, I would absolutely never never never even contemplate having sex with more than ONE while dating any number of them.

ABSOLUTELY utterly beyond the pale, perish the very thought, it is how I am wired, that's all.
