The Crabby variation of the Bull position is a physically demanding yet rewarding sexual position. The woman is elevated by her arms in a supported crab position, which requires significant upper body strength. This position offers better mobility and a wider range of movement compared to the standard Bull position. The man, while still having limited mobility, can use his arms to assist the woman and enhance her movements. This position allows for deeper penetration and can be highly pleasurable for both partners. However, it's important to communicate and ensure that both partners are comfortable and safe during the act. It's also recommended to build up to this position gradually, starting with less strenuous positions to avoid injury.
