The Glowing Triangle – position #40 of 100 Kamasutra Sex Positions
The glowing triangle position is a simple, yet extremely effective, twist on the classic missionary position.
The woman lays on her back, while the man moves on top of her. But instead of laying on top of her, he gets onto all fours and she has to raise her pelvis so he can penetrate her. He then stays still and she does all the work.
