I'm wondering how other single parents have dealt with this or are planning to deal with this. My kids are aware that many other kids have dads, living with them or not. They know that people who love each other may choose to live together and in some cases get married. They don't know anything about s*x yet. We have talked about bodily autonomy, and discussed that people should not touch certain parts of the body or ask kids to touch their bodies.
I feel it would be good to introduce these topics gently, for their own safety now and also to make sure s*x does not turn into some huge taboo. I'd welcome your thoughts or experiences.
