Can love change a pyl in a way that hinders a BDSM relationship?
Good question. I can only attempt at an answer from the pyl side, since it's the only side I've had active experience in. So far, I would say no, from my side alone. The more my emotions are involved, the more attached I become, and the deeper I care about someone, the more vulnerable I am willing to be and desire to be around that person. That vulnerability is a necessity to complete submission for me (perhaps not with everyone, but for me, yes). I can tolerate more pain from someone I love and trust, and the entire situation involving physical pain goes so much better for me when it's with someone I love. I know that when the scene is over, he will be there to essentially put me back together. Hopefully that scene will have increased our bond because it will have allowed him to get past yet another layer of defenses. S&M for me really is a bonding experience, so I don't really see how love would decrease that. If anything, in my limited experiences, love has nurtured the BDSM side.
