Scope of article wrong?== 
 Sexual intercourse, specifically coitus, is the human form of copulation. 
 Is this correct? I do not think this is right, why should the term apply only to humans? There's this definition Sexual activity during which the erect penis is inserted into the vagina where ejaculation takes place. from here This definition seems to be exclusivelly about human activity  sexual intercourse, intercourse, sex act, copulation, coitus, coition, sexual congress, congress, sexual relation, relation, carnal knowledge (the act of sexual procreation between a man and a woman; the man's penis is inserted into the woman's vagina and excited until orgasm and ejaculation occur) (from here), though it does not distinguish between copulation and sexual intercourse as wikipedia does. Then there's this Sexual intercourse: Sexual activity that involves vaginal, anal, or oral penetration from here. And why should there be seperater pages for sexual intercourse and copulation? This seems daft to me, but maybe I'm just looking at it from a biologists POV.
