In the split variation of the Sinner, the woman lies on her back with her legs spread wide apart in an outward splits position. This allows for deep penetration and can be particularly pleasurable for both partners. The man can hold her thighs in place to maintain the position, while she can hold on to his arms for added stability. This position also allows for easy access to the woman's clitoris for manual stimulation, which can enhance her pleasure and increase the chances of reaching orgasm. It's important to communicate and ensure that both partners are comfortable with this position, as it can be physically demanding for the woman. Additionally, using a pillow or cushion under the woman's hips can help to alleviate any discomfort and make the position more comfortable for both partners.
