Just slide your fingers in straight like your penis does and feel the top of the womens vagina inside and feel as your finger goes deeper about 2 to 3 inches in and your fingers will go up higher all of a sudden and you will feel a ridge.
Bump like texture in her vagina now. Just like when you roll your tongue along the top of your mouth directly above your tongue. Then you put your two fingers on that spot in the middle of that ridge.
Hold your finger there
The E-I reference system allows users to give other users a "reference" if they have met them in real life and are happy to recommend them. Only users in escort usergroups can give escort references. Only users in the "Established Clients" usergroup can give client references. Where you see a user has references, although you cannot see who gave the references for privacy reasons, this shows you that others have chosen to recommend the user, and may help you decide whether or not to trust him/her.
