“In cowgirl, you lay on your back as your partner rides your cock. This is a great position to get comfortable and relax as your part- ner moves in the ways that feel best to her. Let her guide your cock to enter her.
Your partner can fuck you while she’s on her knees, or she can squat over you with her feet on the bed; both variations create different sensations. You can watch her touch her clit and pay attention to how she moves her fingers as she thrusts.”
