In the Collapsed variation of Doggy, the man assumes a kneeling position but then lowers himself so that he is resting on his calves. This position is easy for him to maintain but limits his mobility, allowing only for slight pelvic thrusts. The woman takes the lead, controlling most of the movement by rocking forward and grinding against her partner. To enhance comfort, it's advisable to place some pillows on the floor for both partners' knees. This modification of the traditional Doggy position can provide a more relaxed and intimate experience, with the woman in control of the pace and depth of penetration. Communication is key, as both partners should express their preferences and comfort levels throughout the encounter.
