Do you have reason to believe that is what he has planned? I know it is hard not to think that.
From the asses (oops... that's horse's isn't it) mouth. He wants to "experience new R's up to and including falling in love."
I realize it may not be about the sex. I just find it funny (in a dark and twisted kind of way) b/c I was the one who always wanted sex, not him. Could be he needs to feel needed and appreciated in a way he didn't get here. He isn't a talker so he leaves you guessing (always has) as to what he needs or would like.
I'll pass along any insights I get from DB coach in just a little while.
