missionary position

male-female sex position: the woman lies on her back with her legs apart and the man lowers himself on top of her, supporting his weight with his elbows, and enters her with his legs either inside or outside hers (usually inside). He may lower himself onto her and rest more of his weight on her body. The woman can wrap her legs around him to control the depth and speed of his thrusting into her vagina, or she may thrust a little towards him from her pelvis to match his movements in and out of her vagina.
