I was sorting clothes to wash today and while seperating I discovered a pair of my fiancee's boxers. I knew right off what it was, I saw several dried stains in about five or six differnet located at button and around area. But I saw on the inside of waistband, about an inch in width ,from top to bottom, a stroke stain, and even the whole area where I examining was stiff. I confronted him on these infidelity issues(I'm on my period all week and the clothes are 3 days old) He claimed it was masturbating outside of boxers.I believe he's being unfaithful, but I want to know what the different styles of stains mean and could they all come from one self-induced orgasm or was he basically having a quickie.He keeps telling me I'm stupid and crazy. I need validation confirmed so to prove I'm not insane and solid proof from a professional that I am correct and leave while the gettings good.
