The Squatting 180 variation of the Pile Driver position is the most extreme of the bunch, which is really saying something given the reputation of the family. Requiring an erection that is able to aim backwards, many men will find it difficult, if not impossible, when fully aroused. Even those who are able will find it tricky to achieve penetration. Consequently, it may be better suited for men to receive anal penetration from below. For those wanting to try the vaginal form, we recommend transitioning into it from the 180 or the Grounded variations, and taking it slow to avoid risking injury.
