If you're just slammin' it, it don't really matter much, in fact, a full bush can tickle just right. When fucking. Visually, nothing says "I love you" like a bald pie, on the right girl. We also thoroughly enjoy both the triangle and the landing strip, and I personally over-appreciate any whore willing to put time in on a lighting bolt, a heart, or a flying V. All that being said...
SMOOTH LIPS!
...Whatever else is going on down in the jungle is fine (neatly trimmed please) but visually, we want to see the lips. Then we want to kiss you on your lips. Who wants to kiss hairy lip? I have, but I much prefer the smooth lips.
As for hygeine...
