There are many common positions in sexual intercourse. You can let a man lie on a woman and a man sit on her. It's the same as the first one, except that the woman's leg is on the man's shoulder and three women are on the man's shoulder. Same as the first one, but switched places, four women lying on their sides, their legs bent, and so on. If you try one more time, you will know. In fact, the position is not limited, as long as it can be inserted into the vagina.
