I'm telling you... go with the clown look. Coulrophilia! It's a thing, and you should capitalize on that **** because chicks dig clowns. Also, remember to bring a handful of glitter. When they're going down on you sprinkle it on their heads. It makes it a magical experience for everyone...
Seriously: It really does seem to vary by generation. Some of the younger women seem to prefer less hair, some of the older women seem to prefer more... but even that's just apparent averages. It's a matter of preference, and varies woman-to-woman. There's no right answer. Probably best to go trimmed and adjust as necessary...
