Caught in a Web
This one may not exactly qualify as a position, but it would certainly be a physical feat. Caught in a Web involves a person who is carefully tied into a 10-by-10 foot "web." The person in the web is positioned in sexually available ways, and the free partner can work with that however everyone sees fit. Tiger Devore, clinical psychologist and certified sex therapist, says this web was one of the most artistic and sexual positions there is.
