I have alters that are children and totally freak out about anything sexual. I explained that it's normal for me as a grown up to have sexual needs etc.. and the children don't need to be afraid. They don't need to be present for intimate sexual moments. If they do pop up (the kids) and are scared, i stop and my b-friend and i go for a walk or something. I have DID.
