What's normal during a massage?

[love]

When I am on my stomach getting a massage, after the the lady is done with my back, she covers my back and pulls the sheet up to my butt to massage the back of my legs. It feels weird to have my butt "out there". I love the massage she gives me, she does a great job on the legs and butt. An alternative is to wear panties to cover, but I do not want massage oil to get on them and ruin them. My friends say I am too self conscious and just relax. So, is this normal massage practice, and should I not worry so much?
@ Lester Yes I have had another therapist do it one leg at a time and you are right only half my butt is exposed...it is still awkward knowing my butt is out there...lol Thanks for your answer very thorough I like it!!
@ Candice LOL what a descriptive story. The few times a guy has massaged me, it does get a bit "exciting" at times wondering what is going to happen, especially if he is good looking. Probably just in my mind me thinking too much though, kind of like why I asked this question. Thanks for your answer (and honesty) made me smile )

love Thanks for this sharing info And at least for those first few hours after a massage, avoid caffeine and alcohol, which are dehydrating.
