Sexual intercourse (or coitus or copulation) is a sexual activity typically involving the insertion and thrusting of the p**is into the va**na for sexual pleasure or reproduction.[1] This is also known as va**nal intercourse or va**nal sex.[2][3] Other forms of penetrative sexual intercourse include anal sex (penetration of the anus by the p**is), oral sex (penetration of the mouth by the p**is or oral penetration of the female genitalia), fingering (sexual penetration by the fingers) and penetration by use of a d**do (especially a strap-on d**do).[4][5] These activities involve physical intimacy between two or more individuals and are usually used among humans solely for physical or emotional pleasure and can contribute to human bonding.
