Anal sex or anal intercourse is generally the insertion and thrusting of the erect penis into a person's anus , or anus and rectum , for sexual pleasure. While anal sex is commonly associated with male homosexuality , research shows that not all gay males engage in anal sex and that it is not uncommon in heterosexual relationships. As with most forms of sexual activity, anal sex participants risk contracting sexually transmitted infections STIs. Anal sex is considered a high-risk sexual practice because of the vulnerability of the anus and rectum. The anal and rectal tissues are delicate and do not provide lubrication like the vagina does , so they can easily tear and permit disease transmission, especially if a personal lubricant is not used. Strong views are often expressed about anal sex. It is controversial in various cultures, especially with regard to religious prohibitions.
Sexual intercourse is sex with penetration of the vagina or anus by a hard penis. A man who is aroused can get an erection. The penis swells with blood. It gets bigger and harder and it rises up. If you do not have a desire to have children at the moment, use contraception.
Like most girls in her neighbourhood in Tehran, Tahmineh is a virgin. In her world, virginity is still revered. Virginity is seen as a marker of decency, of good family stock and morals. Women live under constant risk of being branded loose for behaviour as anodyne as laughing too raucously or wearing the colour red. Tahmineh wears the all-encompassing, black chador because her parents insist on it, and because neighbours in her conservative community gossip about women who choose to wear the headscarf and manteau, the overcoat that is meant to keep curves concealed. But in Tehran, being a virgin does not mean that Tahmineh has not had sex. Tahmineh believes there are rising numbers of girls like her, who are from religious or traditional families but prepared to experiment sexually before marriage. For more than 30 years, the Islamic Republic has been obsessively battling against sex.
