What we choose to call sex is really one part of a much bigger spectrum. Passion, lust, romance, flirting, courting, caring, attraction, "chemistry", all have their own colors somewhere on that imagined rainbow. It's more subtle and nuanced than we usually think.
Roses, it is very gratifying to see you think things through on the level you have been, and come to your own conclusions, realizing what your boundaries are, owning this whole aspect of your life for yourself.
