New clients who try this are told it doesn't do anything for me. Years ago I had a regular who would finger my g-spot eagerly every booking hoping for me to explode into orgasm. I never did because I need different type of stimulation and we never got around to it (part him, part me (dealing with other difficulties I had with him)). These days I simply make it clear deep fingering does nothing, if they hurt me I tell them, I will then if they are interested show them what does work for me.
