I'm 22 and a student working towards being a Registered Massage Therapist. There is the obvious concerns in the industry, of inappropriate sexual contact, something that is covered extensively in class.
We students practice daily on each other with one student being released for inappropriate behaviour. It is a constant concern.
I being a black male, the only one in the class, they all believe the big cock, the well endowed stereotype. In my case its very true. I have just shy of 10 inches of length and a very healthy girth. Believe me I've had more than a few brushes of the accidental nature while being used for practice by both male and female students.
There are many women in my past who had to have pics of my dick in them, on them, around them. Crazy to think of such but they want to show friends I guess of my porno size cock in their holes.
Erections are the norm when working on a male in class or out. We are to ignore the situation and let the customer know that such arousal is normal and not to be embarrassed.
Having said that, I have suspected that my fellow classmates have intentionally "by accident" brushed up against my balls and unit in hopes of igniting my erection.
One class, our instructor, a gay male, used me to illustrate the proper technique on massaging a groin pull and lower abdomen injury. I'm not gay but while his hands were manipulating me under the sheet my cock grew which pitched a substantial tent that was the awe of the class. They all giggled and out and out laughed at the size. The instructor chastised them, their behaviour was extremely inappropriate. Although, I didn't mind.
After that moment the increase of accidental touching of my package was substantial. Also, I might add, was the attention of our instructor.
I'm by far not the best student and have asked others for their assistance in after class practice. This is common for classmates to help each other on the practical aspects and techniques. We use family members and friends as well. Of course when doing these practice sessions, proper etiquette can be ignored if both parties decide to do what adults often do. What happens on the table, stays on the table.
