Sexual cousin???

Brea

My boyfriend and his cousin are best friends. They talk ALL the time and work at the same place.

The issue? I checked his email today (looking for shipping information) and I saw an email from her that contained a comprehensive list of her sexual fetishes that were ranked by her from 1 (least liked) to 5 (most liked) and at the bottom she asks him to send her back a list of his using the same ranking and they'll compare and remove the 1 & 2 ones.

I'm very confused why they would need to compare fetishes??? Please, give me your opinions please.

**edit: he didn't respond to it in emails but now I'm sketched out....
