Okay, this is probably as steamy as I've got so far. I did this once a number of years ago, just out of general curiosity (I was still in high school, and not at ALL sexually active). Years later with someone I was engaged to for a while (broke it off, don't ask) both of us started doing it.
That only lasted as long as the engagement did, until the start of 1998.
In April 2001 I started it again, and still do it fairly regularly, though there's only been one partner who's 'known' about it if you know what I mean. She seems to like it.

Now with her, it's interesting. I've seen a few ladies who'll do the labia/vulva and either leave the entire top part bare, or a landing strip, or leave fuzz above the top of the labia/vulva. She's done the opposite. trimmed the labia/vulva, and shaved right down to the top of it.

But I digress
