Professional electrolysis experience/help

Hey y’all! I posted in professionals only but that thread doesn’t seem to get a lot of views. I am looking for help/education on best practices when it comes to female bikini/Brazilian electrolysis (positioning/skin stretching to get best insertions). I have a client, who is a friend, and I find working on her very difficult.

I have been able to obtain a video for educational purposes on male genital work but I would love any and all help for female Brazilian. Feel free to message me or respond in the professionals only thread as this is a mature topic.
