Avery Another aspect that troubles me about talking to Dad is that if I were to introduce the topic to him when I was 15 it would play as "this is how I'm going to start out in life". If I introduce it at 20, which I am now, it might emphasize that I have not been conducting myself in this fashion. and I don't think I want to draw any attention to that.
From what I have read about you, you are actually an open person and have no problem showing your assets. Your father knows that and has it in mind that you do not dress too revealing. I think he will also have noticed that you have had sexual experience with men. In addition, your rape, which you have processed so far well and now wear for your own protection from time to time the CB.
The CB is directly linked to chastity and so it is not unusual or strange when you deal with it. Why don't you talk to your father about this issue, how it was and was seen in the past and how it is today. Thereby you can exchange yourself freely with him without first going into whether you want to do that or not. You have also had some discussions about this topic before you came to the decision and so you can also do it with him. In the conversation or a later you can deepen this whether it would be what for you. I think if you want to know his opinion he will be happy to help you without getting suspicious that you actually want something else.
By the way. As far as I remember you write about your siblings and father. Is there also a mother with whom you can talk?
