In this subtle variation of the Climber position, the woman controls penetration, which may seem hard at first but requires just little practice. The results may be surprising, as difficulty may surprisingly turn into new and very pleasant sensations for both players. This position requires a lot of physical effort by the woman, as she holds her partner's back while jumps up and down. The man here only sustains the partner by holding her by the hips or thighs. It's not a position recommended for prolonged sex, as hard to keep up for long, however, it can be really intense.
