All of mine have, too. I found out recently that my wife, who maintains that my cock size is "perfect - not too big, not too small," has been cheating on me from the beginning. (I'm 5 " long and 4.5" around). Been to together 19 years and her ex-friend told me that she used to see this black dude on a regular basis for about 5 years. She knows because she introduced my wife to him. The slut recently got hammered by one of the guys doing construction next door while my mister and I were camping. I found cum stains on the comforter and everything. Though it appears that I may be slightly larger than you, don't feel alone. Anymore I think that most everyone cheats if given the opportunity.
