Hello everyone, First time here, I am married three years, together for nine. I have two daughters 17 and 15. My husband also has two daughters, 17 and 15. All great girls. My step daughters are sexually active mine are not. My 17 SD, I've heard, has been sneaking her Boyfriend in her room in the middle of the night (also happens to be her 2nd cousin). My husband is aware and doesn't seen to bother him much. I, on the other hand, think it is so inappropriate and disrespectful. I don't know if I should just let my husband and BM handle it? It is my house, should I put my foot down?
