B/P check

It seems like... every time I get a B/P check, the nurse ends up with my hand very close to or touching her breast. Is this necessary for the nurse to hold someones arm in this position or is this a tease on her part? Sometimes, with a good looking nurse, I feel like a little squeeze.

I had a cardiac ultrasound last week. The tech was a young, hot lady. She had me lay on my left side for the procedure with my right arm along my right side. She was set up with her equipment at my back so had to reach over me with the ultrasound sensor with her right hand. She was fairly short so my arm was in contact with her right breast for the entire process. I was wondering what my wondering mind and hidden erection was doing to the results of the test.
