Q: Can I be your assistant?
A: No. Anyone who asks this generally just wants to be in the same room with naked women. You will be no use to me standing in the corner trying to cover your erection. If you want to see naked women IRL, go to a strip club and pay them.
In reality, although I would love to have an assistant, it's another person in the room. A lot of people need a long time to be comfortable being naked / sexual in front of other people. The model's comfort is always top priority.
