i find that its easier to remove hair from the clients underneath area is by getting the client to kneel on the couch with her elbows and forearms resting on the couch. That way the botttom is kind of sticking in the air and because of the position the skin is perfectly stretched and easy to wax. Keep the chat lighthearted and she wont get embarassed. The client will only get embarassed if you appear to be or you dont appear confident in what you are doing... i always have great music on and chat away so they dont think about the position they are in............
