Waxers often get asked questions like "is this the most hair you've seen?" or "am I the biggest baby you've had?" and almost always, the answer is no. As Barshop explains, "there's always somebody worse."

However, there is something you can do that will gross out your waxer: not clean up beforehand. Shays says at least twice a week she has to send a client to the bathroom with a wet wipe because they have poop on them. It's awkward for the waxer and mortifying for the customer, so clean up before your appointment to avoid the whole issue. Nacion says unfortunately, about 10 percent of her customers don't freshen up before their appointments (even if they've been to the gym or just got off a 12-hour flight) -- and it's usually the people who think they're fine that need it the most.

Turns out, some people don't know that a Brazilian wax means everything (yes, everything) gets taken off. So if you don't want to be hair free from your bikini line down to and including your butt, opt for a basic bikini wax. A good waxer should also explain to you what a Brazilian entails the first time you get one, but even after doing that, they say some women are shocked when the waxer heads towards their rear.

Barshop says one client freaked out and froze after she had applied the wax, she refused to let Barshop pull the strip. They had to cut the wax out of her hair. She eventually opted for laser hair removal instead.

Shays shares a story of one of her clients: "One client had been waxing with me for about five years with no problems, and then she got a new boyfriend. She went in for a Brazilian and called five days later saying she was really itchy and she thought she had gotten an infection from the waxing. She went to the doctor and it turned out that her new boyfriend had dirty hands and staph bacteria on his penis and he had given her an infection."

The moral of the story? Waxing removes the top layer of skin, making it easy for bacteria to get in. A good waxing salon will keep you safe while you're there, but then it's on you to keep yourself germ free.

Waxers get some pretty odd requests, but they're almost always happy to oblige (so don't be shy!). They often get asked to make shapes in pubic hair (triangles and hearts are common and pretty easy to do) and Shays says one woman asked for an arrow pointing down (maybe her partner has a poor sense of direction?). Barshop says her craziest request was from a client who wanted a skull made from Swarovski crystals applied to her bikini area for her wedding day (wonder what message she was trying to send?).

Other requests include waxing body parts like ears, nostrils, and even nipples. Nacion says many pregnant women have increased hair growth and come in to have their nipples waxed.

Shays, Barshop and Nacion all say about 15 to 20 percent of their clientele are men, and the numbers are growing. And don't think all those men are gay or metrosexual either; there are plenty of average Joes going in for chest, shoulder, back and even butt and bikini (yes, bikini!) waxing. There are even some brave men out there getting Brazilian waxes too.

Shays says there really isn't much difference between waxing men and women -- both get into the same positions (although guys have to hold their skin differently during a bikini wax, for obvious reasons). She will say that most guys have coarser hair so waxing them tends to take longer, and she also revealed that men tend to have a lower pain tolerance than women (so much for that tough-guy myth).
