I think it's necessary that he writes down every encounter in the same way. Because it might be very different to do the same way with his significant others, whom he blindly trusts, - or me - and other people.

I'm fine with not seeing them. But I want him to do the writing things down. That way it would be private still - and if both you and Lucas, and me, talk about what notes he took on sexual activity with us, I'm sure that would be helpful and guide him into thinking about the rest himself. [He frowns, and bounces slightly on his feet, forth and back.] I didn't think he would freak out that much.
