It’s really just a WAG though! Give it a try from the side…that position is guaranteed to take everything as deep as it can go and there are variables on both sides of the glans that make it tough to say “this is the magic number”. Also from this position you can stroke the front wall of the vagina and hit the G-spot up front too…and that one seems to be fairly shallow.
