Doesn't bother me any when with the right person (i.e. spouse). I was eager to earn my redwings some years back with the girlfriend. I do think of it as an activity best reserved for those that can make the much dreaded BBFS list though (by this i mean one's personal list in life, not some super secret "hobby list"). Doesn't seem like a good activity to partake with someone you wouldn't even want drink with from the same glass.
