I agree, Riven, that is a lovely description that rings true to me. In this, I've come to the conclusion that I probably think more like a male when it comes to this sort of thing. (Yes, I know there are exceptions but generally speaking.) Physical affection and ML is the ultimate bonding experience for me. Nothing else comes close, and without it I just can't feel fully loved. Also, bouncing off the topics of a couple other threads, I'm not bothered by porn or erotica (okay, not counting violent or extreme stuff here) and have found it to be helpful and kinda fun in past relationships. Although extremely painful, I can theoretically see the potential for moving past an EA, but just the thought of a PA makes me completely and utterly bat$h*t crazy.
Remember that Friends episode where Ross and Rachel are fighting over a girl he slept with while they were on a break? I had something similar happen with a boyfriend years ago. We split up for awhile, and then were getting back together, with both of us SOOOO happy about it. We were close to ML and he told me beforehand that he had been with someone while we were broken up. I will always respect him for his honesty, and I will always love him, but I could never get past it, although we are still friends years later, and have lovely memories of our time together.
By the same token, I could not stay emotionally connected to one person and be physically intimate with another. I would be doing harm to myself emotionally and psychologically, and be betraying my own personal ethics. I would have to make a clean break first.
