Do most men (husband or boyfriends) trim their "back" hair?

Ladies and men, do most men trim the hair on and near their rear? I am wondering if other wives have husbands who do not and what percentages exist. My husband does not do so but I am very glad for it. I am one of the grateful people who can appreciate a man's natural musk. This is probably because I had a fecal obsession as a child (yep, full on rectal digging and everthing! And proud of it!). I attended many, many sessions of behaviour therapy to curb my habbits. Once I turned 17 I no longer dug or had fascinations with rectums or feces. It wasn't until after having to change the diapers of our first child that these desires returned. I have managed to stay away from myself (for the most part) because my husband likes anal play performed on him. Lucky for me he also doesn't trim as much as others might. So ladies, what do YOUR husbands do? ;)
