In the sex position "Woman on top (cowgirl, with penetration of anus)", the woman sits on top and controls the pace and depth of penetration. In this variation, it involves anal sex where the man penetrates the woman's anus. This position gives the woman control and the opportunity to stimulate her clitoris at the same time. It can provide an intense and different sensation for both partners and can be a tantalizing experience for those who enjoy anal stimulation. It's important to start gently and use plenty of lube to minimize discomfort or pain. Always make sure to listen to your partner's signals and respect their boundaries to ensure a comfortable and safe experience for both partners.
