I feel really bad about asking this, but I dont know what to do. Im a single mom (my husband passed away a few years ago) with twin girls. About a month ago I caught both my girls masturbating and I just told them it was a normal things to and left it alone. Last week I caught them masturbating again but in the same bed, and it very freaked me out, and I havent spoke to them about but I think that I need to. What should to do?
