Trimmed for sure, shaved around certain areas. I trim, I don't want to eat pubes and I don't think any girl I've been with wants to either. Maybe I'm an ass but I refused to go down on this girl because of her "amazon forest" trimming is easy, very low maint. As for shaving, have to do it everyday if you do it (easier for porn stars tho, just do it before the shoot, and don't give yourself razor burn..).
Waxing is the best for the no hair look, and the hair doesn't grow back for a lot longer, sometimes it also thins it out if you do it repeatedly. I did it once... never again, fi you think about it, and you're a guy (or maybe a really hairy girl) wax your chest first, very sensitive there too.
Dunno about nair tho.. may be a nice alternative.
