I try not to sleep with people I think I could find adoration within. Mind you, it doesn't always work. I have feelings for at least one of my lovers who we engage in threesoms with, but that's a long story and her own affairs make it too difficult for me to have a relationship with anyway. So I'm in this one, just for the sex.
I'm actually looking for a wife/girlfriend who enjoys things like being shared. Makes it a bit difficult....
