Several months ago my wife switched to wearing thong underwear when dressing for work saying that she was trying to eliminate VPL. More recently I bent down to pick up some dirty clothes to take to the laundry room, including the thong panties she had changed out of upon arriving home from work. When I picked the small pile of clothes up I felt something sticky, and wet. When I got to the Laundry room I realized the sticky wet stuff was in the crotch area of her thong. Although it appeared similar to semen, it was not the same consistency. there is rarely a day now where I don't notice this substance in her thong, and some days the amount is substatial. Could she simply be getting aroused at work? Masturbating? Or, having sex with someone? Being a man I obviously don't know the first thing about vaginal secretions.
