Sexual intercourse or coitus or copulation is sexual activity typically involving the insertion and thrusting of the penis into the vagina for sexual pleasure , reproduction , or both. There are different views on what constitutes sexual intercourse or other sexual activity , which can impact on views on sexual health. Various jurisdictions place restrictions on certain sexual acts, such as incest , sexual activity with minors , prostitution , rape , zoophilia , sodomy , premarital and extramarital sex. Religious beliefs also play a role in personal decisions about sexual intercourse or other sexual activity, such as decisions about virginity , [13] [14] or legal and public policy matters. Religious views on sexuality vary significantly between different religions and sects of the same religion, though there are common themes, such as prohibition of adultery. Reproductive sexual intercourse between non-human animals is more often called copulation , and sperm may be introduced into the female's reproductive tract in non-vaginal ways among the animals, such as by cloacal copulation. For most non-human mammals , mating and copulation occur at the point of estrus the most fertile period of time in the female's reproductive cycle , which increases the chances of successful impregnation.

The Supreme Court's landmark ruling Wednesday criminalising sex with wife below 18 has cleared an inconsistency in laws that differed over the legal age of sexual consent. Former Union minister Chinmayanand, accused of raping a year-old law student, was arrested from his residence in Uttar Pradesh's Shahjahanpur district on Friday. ET has accessed the court orders by which bail was rejected on September 30 for both Chinmayanand and the girl in the respective cases lodged against them. Chinmayanand, who was arrested on Friday and and sent to 14 days' judicial custody, was shifted admitted on Monday to a Lucknow hospital, where he was tested for cardiac problems. The student has alleged she was raped and physically exploited for over a year by Chinmayanand, who was arrested last week and remanded to judicial custody for 14 days.
