So...I am speaking of the woman simply laying totally flat on her tummy on the bed (or floor). Her legs are together. The guy straddles her, legs on either side, like a saddle and then inserts his penis into her rear, after spreading her cheeks with his hands to access her rosebud. Maybe since my guys penis will not angle down like that (without breaking) so it "pulls up"? I don't know. We just tried it again, and it is not happening.
Anyone else ever try this position and enjoy it? Oh...his legs end up pinching my legs on the outside, when we try this too. Ouch. No fun.
