How many men your wife sleeps with

My wife and I have been in this lifestyle for a couple years now. It all started when we were having sex and I told her I thought it would be hot to watch someone fuck her. After a lot of talk and back and forth, she finally agreed to try it. The first guy was my closest friend. At first, she didn’t really like it but does think it’s hot now. She currently has 3 guys on the side right now not counting me. One is 28 and single, one is 37 and single and the other is 34 and married in our neighborhood which I think is really hot. When they come over, they usually hang out and have some drinks and then they go in the bedroom and fuck and I stay in the living room usually.
In total, she has fucked 8 guys since we started this. I was just curious everyone else’s situation and stories.
 
That I know of 3. All 3 were behind my back. The first one was when we were dating and I was deployed. The second one was after we were may and we were having "Troubles" And the third one she told me on our anniversary night out was about 2 years ago 2 years after I told her I would love to share her. I'm sure there was more. More and more come out when she drinks and gets high.
