I noticed my son's recent behavior has been strange. He suddenly started hugging me from behind while I was doing housework, and began staring at me in the bathroom. Once, I even found white liquid on the crotch area of my underwear. On another occasion, he offered to massage my shoulders, but his touch quickly turned clearly sexual. I never imagined my own son would do such things to me, and it shocked me deeply. I felt extremely uneasy knowing this was happening right under my husband's nose.
