Ok I have tried to bring this up with my two brother in laws a few times in the last 10 years but I get no where. There have been times when the topic of sex comes up but its that non meaningful hinting to wanting to have sex more often and laugh it off deal. I wish we as bros-in-law could just be open and not just talk about sports, vacations, and work. Anyone else have a open discussion with their bros-in-law about their sex life with their wives (your wifes sister) or talk about size ect?
