I've just had my bikini line lasered, too - three sessions down and one left to go, then yearly top-ups. I've only done the 'triangle' area at the front because it was quite excruciating during the first session but much improved for the second and third one. It's a good idea to take a paracetomol with codeine (over the counter tablets) or two about half an hour before the lasering starts, if you can!
I don't mind shaving in general, it was just the irritation and in-growns that were driving me mad so I'm really glad that the whole area is super-smooth now. I'll probably get legs and underarms done in winter (when I'm all ghostly pale again, meh) but if they'd hurry up and invent lasers that work on darker skintones I'd get everywhere done right now!
