In a past relationship we would discuss this topic in depth. She said, it was the fact of doing something
extra naughty, the
taboo nature of having sex with a man who is not her boyfriend (me) in his (my) presence right before her man's (my) eyes which added greatly to her arousal which in turn provided for a very hot and special experience. Plus, the opportunity of having something
new and
different every once in a while.
She also described the moment of the experience with the other man as "
unwrapping a present", when she is in anticipation of what will come. What will he (and his dick) look like naked? How will he handle her? Will he be a more tender lover or will he just f*ck her hard? What sexual play and positions will he prefer and go for? Will he be able to make her cum? Give her multiple o's? Or even make her squirt?
In the end there wasn't a single man like another, and no experience would ever compare to having sex with me, the man she loved! See, love and pure lust are very different feelings.
Of course our love included us lusting for each other, and our playdates that would involve another man were built on the love we had for each other, so love was always there. It was between me and her however, not her and the other guy.
She is a Woman who is able to enjoy sex greatly as a pastime, so to speak, without falling in love over it. A word of wisdom and warning: If that doesn't describe your Woman well, better not start a lifestyle of sexually sharing her but keep it just your fantasy instead!
