Story with my wife a little more different. We don't know how many men she had, because when she went to university, she was fucking (for money) to pay for her studies. She did that for around five years, and during that time she had around 20–30 men per month.
We met a few months after she stopped doing that, because she had experienced some violence. A year later, we started sharing, visiting swinger clubs, and similar fucked up activities. Up until now, since we've been together, she has been with around 150 men and we had some beautiful and crazy stories.
But she never had any true gangbang the maximum was four at the same time. On my HB, she had 8 men, but they had sex with her individually over the course of the day.
What she really likes is FKK, walking naked in nature, and teasing other guys. 😉
