Personally, I trim most of the time, shave the sides if I'm going swimming.
But if I'm on the pull, I prefer to leave as much as possible. A full bush is like a barometer. If he doesn't like it, and thinks it's his place to comment, then I know he's a tit and the relationship will go no further.
My flatmate went to the gym the other day and said "there was a woman next to me in the showers with a MASSIVE bush," and I'm like "er, ok." I mean, who fucking cares, why would you even notice?
I can't believe how much things have changed in 10 years. When I was at university, no-one I knew waxed it all off. Now it's just the norm, and if you do any different, it's like "eugh, it's dirty." Get a fucking LIFE, it is PUBES, not a flea-infested sewer-dwelling rat.
Shave it all off, wax, trim, leave it. Whatever. But don't give me this shit about it being cleaner because that's just some shit that marketing people came up with to make you buy their stuff.
And as for men shaving their pubes, well, fuck, it just doesn't look sexy at all to me. Way too groomed and footballery. The image of a man hunched over the bog trimming himself with a pair of nail scissors is just le boke.
