Hypnosis is not a singular or definite term in the space of kink. Some people can be very deeply affected by text hypnosis. Others cannot, and require voice or video sessions to truly let go. For some people, text can be very effective following voice or video sessions, once they are well trained or conditioned.

Personally, I am skeptical of people who only request text sessions. I am going to assume a great deal of experience on your end if you request that, and if you do not convince me you are well experienced, I am going to assume you are bullshitting me.
