For partners looking for something new to try position-wise, Marin recommends the website Bad Girl's Bible. It shows positions using clothed models in educational ways. The positions are broken down by category, such as "exotic" or "standing" positions, and easy to understand. She says this site offers an opportunity to discuss new possibilities with a partner in a low-pressure way. For partners who share gym memberships and are in top physical form, check out our favorite sex positions for athletes.
