Kim Anami does! She is an intimacy coach and she uses her vagina to lift various things. Some of those things include surf boards and coconuts. She says it strengthens the pelvic floor and it increases the ability to enjoy sex. This is definitely bizarre, but I am also intrigued! What Anami does is ties a string to a jade egg, which is inserted into her vagina. The string is then attached to whatever item she wants to lift.
