Which position is best for having sex?

There are quite a lot of different positions for sexual intercourse. One of the most common is the missionary position, where a woman lies on her back and a man lies on top of her. A man and woman might also lie on their sides, the woman may sit on top of the man, or she may kneel on all fours while the man puts his penis into her vagina from behind. If a couple are in a position where the woman's clitoris is not being stimulated, they can do this with their fingers.
