Kenny you've asked lots of questions, hopefully I can answer most of them.
Met her when she was still a teenager and in school. I was 29. At the time I was her boss and we were no more than friends and co-workers. I had actually first met her five years earlier but she swears she doesn't remember, although I have been able to prove to her it happened. She was a member of a softball team a friend of mine coached and i followed him around when they played. I only remembered her because she was a really good player for her age.
When we worked together, she had a boyfriend, and older guy who was out of school. We started dating about 6 months after "meeting" the second time. Two weeks later was the first time we fucked.We married about 7 months later. Yes she was out of school by then.
At the time of our marriage my number was 3. My high school girlfriend, a girlfriend after college and my now wife. Her number was 6, she didn't expand much on it other than to say I was number six.
A few years later, after a particularly bad accident at her work, she was diagnosed with PTSD. During her therapy, she kept a journal or a dairy of her thoughts and memories. Part of the therapy later on was to share some of this journal with me. In this journal she talks about her first time. She didn't really say much about it in the journal but did feel she needed to share it with me. It's not something to be shared here due to forum rules and honestly doesn't matter to the story, other than to say I do know the guy and due to the circumstances I'm not happy with him or willing to speak to him ever.
Because of what happened to her then she thought that sex was how women kept men in their lives, so from then on she was very open in her sexual life. At this point she told me the number she had told years before was a lie. the actual number was 37. Considering her age when we married this number blew me away. Upset? yes but only because of why she did what she did. Over time she did admit that she did finally come to enjoy the act and wanted it.
Do I know of of those guys? I'm sure I probably do, but she's never been willing to talk about it since the time she finally told me the truth. Few details have come out over the years but never names. Yes there were more than one at a time, she admitted to three at once, but I feel it may have been even more from other things she's mentioned since.
For the first ten years of our marriage, I never had any reason to doubt her. Then one day someone knocked on our door. I opened the door to see her boss. The look on his face said a thousand words. She had been called back into work for the night shift that night and took my car because hers had our kids car seats. It was an emergency and she had to leave fast. He asked for her I told him where she was and what she was doing, he stammered a bit and said he was out riding his bike and was in the neighborhood and thought he'd stop by to say hi. Then said it was getting late he needed to go, turned and ran back to his bike. He was wearing wearing those biker shorts, he was showing his stuff and she was supposed to see it.
I didn't tell her when she came home but she did tell me he had called her and told her what had happened. I remained silent and she blew up, "You think I'm fucking him don't you?" she screamed. I have to admit I did think that but hoped I was wrong, her reaction to what happened told me the truth.
Yeah I know the guy, has been a thorn in my side even before my wife and I ever met. Wasn't a friend then obviously isn't one now. So add one. I've wondered how many there were and have been since, I'm sure there have been more. There are two that I do know about. The most recent was an old boyfriend she had chase her hundreds of miles just for a quick fuck. I caught her on that one because of text messages on an old phone. Technically I'm sure he was part of the original 37, but in my eyes he counts as number 38.
The other one i know for sure about was a friend of ours. He was at our house helping us set up our computers to this new Internet thing.

He had just finished helping when he asked was there anything else we wanted? She replied a gang-bang. While nothing happened that night, a few night later he came over and it finally did happen. We did talk about it before it happened and we were both excited by the chance.
He and the two of us got together 6 times total. He moved away shortly after that and it hasn't happened since. So yeah I've seen another man bone my wife, I did enjoy it, tremendously. I wasn't a silent partner, more than once we took turns with her. Nothing got my juices flowing faster or harder than watching them fuck, even after I had already cum. He never used a condom, and came inside her each time. As did I.
Angry or jealous? Not really. When we did our threesomes we all agreed we wouldn't keep secrets, if they wanted to meet alone, I had to know about it. He told me of some of their other times but she denies them happening. He proved to me they were true and she stopped talking to him after that. It didn't bother me that they did it, it bothers me she denies it. So angry, yeah sort of but not because she fucked someone else.
Needless to say yeah I've talked to him about it, numerous times. He even sent me pictures and videos he had. (I no longer have them, sorry.) Yeah it get me hot and bothered, I'd love to do it again. The other guys? Not really I just wish she would tell the truth and tell her stories, I'd love to know about them.
So I guess what bothers me is I'm open to all of this, she isn't.
She has also admitted to sleeping with women. When she first mentioned it I didn't say anything. But when I did ask she did say it happened before she and I met but I could tell she wasn't telling the complete truth. Since then I found out there have been at least three women since we've been married. I've not questioned her on them though because of the one time she did admit to cheating with the old BF and we've more or less moved past it since. I have tried to explain to her how much I just want to know the truth and how it could and would only help our relationship, but so far nothing.
A couple of pictures we took for our threesome friend when we were inviting him over one night. (Yes he came, twice if I remember correctly.)
And some from an old video we made right after we were married. Sorry about the quality, this was long before HD, digital or decent video equipment was afffordable.
