The Best Sexual Position for Spontaneous Sexual Encounters:
The very best is called the standing spoons. Assuming the encounter begins by kissing, once the couple have passed the moment of decision (to or not to), then the man must turn the woman around so she has to back to the man.
The clothes on the upper part of the body are not required to be removed (regardless of how it is done in films), and concentrate on getting the lower clothes to the knees at least or better
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.
