Come clean Eyer. Did you catch your wife - more than once? It must have been more then just seeing her fuck another guy. Was it two guys in your own bed? Was it your best friend? Did you walk in and see it yourself?
I mean you have such a hardon for women having sex outside their marriage and take it so personally that your story must be a real fucking winner.
Get help.
What you really need to concern yourself with is your daughter learning life truths like honesty, integrity, and respect...
...from a sperm donor who screws another man's wife behind his back.
