I am mortified to be writing this, but I'm desperate for guidance. I am a recently divorced 31-year-old mother of two teenaged daughters, aged thirteen and fifteen. My eldest sister's son, who is just a couple of years older than my two daughters, has recently started to make sexual advances towards me. Unfortunately I have to admit that I am rather flattered by his advances and have strongly considered having sexual intercourse with him. I of course intend being discreet and cautious to prevent any unnecessary mishaps. What's worrying me is what this will do to my relationship with my daughters and sister if they find out. Please help. I'm not sure how much longer I can withstand him.
