Quality not quantity... but quantity would be cool too
Before we met, my wife had had 4 different guys. I had been with only 2 girls. She was embarassed to tell me at first because she thought I would think she was too slutty. I told her then that 4 was not very slutty at all and that I prefered girls who liked sex and had experience. I've always prefered slutty girls, even back then.
That was before we started down the path of swinging, then hot-wifing, and now even stuff that qualifies as cuckolding. Now I can tell her honestly that I wished she had had more guys. She says that one of the 4 was a long term boyfriend who for the last 3 years of college the only time they saw each other was when one of them wanted to get laid. "We would meet at my apartment every other day, fuck and then go our separate ways."
Now that we've been in the sex-with-other-people life, I've been with 1 other woman, and she's been with about 12 other guys. It's hard to find quality people. It's easy to find guys looking for a quick fuck, but we are a little picky. Soon we hope to bump our number up though. She recently came to me with a pretty sexy gangbang fantasy that I hope to make happen for her.
