I have read this threat several times and every time I gain new insights from all the opinions that have been offered so far. Depending on the circumstances of each scene I find myself in agreement with Finding Fantasy, Master Kurt, RedEva, Shadoom and his wife.
I have come to realize that as much as I value love as the main ingredient of my bdsm relationship, trust and confidence are just as important. I have tried to see the question at hand from the point of view of all of the contributors to this forum and I have realized that sex is also essential to my current bdsm relationship. Yes, "mental orgasms" are a very special experience but as much as I may claim that my love for my partner is my main motivation my body may beg to differ.
