In the Closed variation of Bumpers, the man's legs are brought together and suspended over the woman's body, providing a unique and intimate experience. This position allows for increased mobility for the woman, as she can control the pace and depth of penetration. However, it also limits the man's mobility, so it's important for him to communicate his comfort level and establish boundaries. To maintain stability and prevent injury, it's recommended to lock hands and ensure a secure grip. This variation of Bumpers can be a great way to explore new sensations and add variety to your sexual repertoire, as long as both partners are comfortable and communicate openly.
