Yeah it honestly makes no sense to me either! i personally hate it! one of my ex's did it all the damn time! its like wait, we just had some hot sweaty sex and now you wanna cover up after all that! wtf? i still wanna see you naked AFTER i got done puttin it in your butt! i asked my girlfriend why women do it, and she didnt have an answer! i guess its just another way to try to mind fuck us!
