This past Sunday, she came in to see her favorite MT, and booked her daughter to see me. That was flattering enough, but then I learned the girl is a minor and had never had a real massage before! When they arrived, the mom said she was impressed with our prior conversation and felt her daughter would be in good hands with me.
I had the mom sit in during the intake discussion, and was fully prepared for the daughter to be too nervous to go through with it. But then I was calm and reassuring and professional, and the girl seemed to be okay with it after all, especially when informed she could keep her undies on.
Wouldn't you know it? Her pecs and glutes needed the most work.
What a brave young lady! Of course, I was extremely proactive about telling her what I was about to do, and why, and so forth. 
Long story short, it was a very nice session. The young lady kept her eyes open most of the time, so we had a nice conversation and I got to teach her a few fun things. She enjoyed the work and felt much better afterward, and was very receptive to suggestions for preventing a recurrence of her symptoms.
Her mom was very happy with the results, too, and she'll bring her daughter back for followups as needed. It was great to have a mother see past the gender thing and focus on what her daughter needed. It was an honor and privilege to be a young girl's first MT, to give her a positive experience that will hopefully help her avoid picking up some of the biases expressed by others.
Great story! Thanks for sharing.
