The ones who only start practicing the technique of the anal sex should take into account spooning anal sex position and its opportunities.
The least traumatic impact angle of the penis on the walls of the rectum is provided exactly at the position of a woman on her left (!) side. A man is feeling himself maximally convenient, allowing him to reach due level of excitation without an effort and orgasm as a consequence.
(!) A woman can hold her hand at the base of a man’s penis, allowing her to ensure herself against the unwanted deep penetration.
(!) By changing the position of a right thigh (higher-lower) a woman is able to change the impact angle, which will make sex intercourse rather comfortable.
