I like the look of pubic hair. I lean towards natural but the trimmed look is OK if it's done right (see below). I don't like the feel of hair on my mouth and tongue, and I don't like spitting out the hairs afterwards, but I accept that it comes with the territory.
Re shaving:
I like the feel of a shaved scrotum, but other than that, I don't like the look of shaved pubes at all. I think they look weird and unnatural. To me, cock, balls, & pubic hair come together as a package and complement each other visually. If there's no hair, it looks wrong, like something is missing.
Re trimming:
The trimmed look can be nice, giving the pubes a very neat, groomed look, but there's a right way and a wrong way to do it. A conservative trim is best, because it looks like you just naturally have very neat, even pubes. Unfortunately, most guys go overboard and trim way too short, making it really obvious that they trim. I think that's about as attractive as a haircut done with a weed-whacker. Personally I think trimming is difficult to get right and generally not worth the effort.
Guys with hairy bodies should not shave their pubes unless they also shave their entire bodies. I'm sorry, but hairy guys with bald pubes just look stupid. If they trim they should do so very conservatively, and make sure that their pubic hair blends in with their body hair.
One of the sexiest things in the world is a guy revealing just a glimpse of pubic hair. But if a guy pulls his pants down and there's nothing but a bald spot where his pubes should be? Blech. :yuck:
