Sex

Sex - also known as shagging, (AUDIO: The Iris Wildthyme Appreciation Society, PROSE: Happy Endings) hooking up, (PROSE: Rory's Stag) and how's-your-father (AUDIO: Visiting Hours, Serenity) - was an action performed by two or more people.

Foreplay was an activity that sometimes was a precursor to sex. (AUDIO: The Iris Wildthyme Appreciation Society)

Some individuals such as Roz Forrester decided in their youth that sex didn't offer anything that Martian ale didn't. (PROSE: The Also People)

According to the Referee, an android visiting Earth, human breeding was "positively vile, and sort of thrilling", comparable to cruelty. (AUDIO: Moving Target)

Sex was also a related but distinct term to gender, (AUDIO: Neon Reign, PROSE: Human Nature, Something in the Water) and a trait which could usually be identified even long after death, though some specimens were nearer the artificial line drawn between them. (TV: Greeks Bearing Gifts) Addressing humankind shortly before the Battle of Canary Wharf, Cyber-Leader One announced that their upgrade to cyber-form would remove, among other things, sex. (TV: Doomsday)

Species
According to the Eleventh Doctor, sharks, birds, bees, and even educated fleas had sex. (TV: Hide)

Whilst stuck in deep space in the 1980s Jason Kane had sex with several aliens. He eventually turned these experiences into several works of xenopornography, including Nights of the Perfumed Tentacle. (PROSE: Death and Diplomacy, Beige Planet Mars) River Song implied that she had sex with an Auton once, telling the Eleventh Doctor, Amy Pond, and an auton Rory Williams that she once dated a Nestene duplicate with swappable heads. She said that it kept "things fresh". (TV: The Big Bang)

Several species have disguised themselves as human and then engaged in sex with other humans whilst disguised, such as the Zygon Kritakh who had sex with Lauren Anderson, (HOMEVID: Zygon: When Being You Just Isn't Enough) the Arcateen Mary with Toshiko Sato, (TV: Greeks Bearing Gifts) and a member of the Slitheen family disguised as Oliver Charles who, around early 2006, enjoyed a number of sexual encounters with Oliver's wife, mistress and a young farmer. (TV: Aliens of London)

It was also known for the Shadow Kin to have sex. Corakinus was described as having “the colours of the mate” before he had sex with Kharrus. However, intimacy was considered a disgusting practice during sex by the Shadow Kin. Kharrus was appalled when Corakinus, under the influence of April MacLean's heart, asked her if they could cuddle. (TV: Co-Owner of a Lonely Heart)

Kragoom, a Great Old One, shagged planets to death. He once tried to do the business with Trull, but Iris Wildthyme and Wayne Bland II thwarted him. (AUDIO: The Iris Wildthyme Appreciation Society)

Humans
Humans were well known for having sex often, enough that John Hart complained that, "it's all just sex, sex, sex with you people." (TV: Exit Wounds)

By the 21st century, humans did not need to have sex to reproduce — the males donated sperm and it was injected into the females by syringe. (TV: Out of Time) Carys Fletcher worked as a temporary secretary at such a clinic. (TV: Day One) However, the majority of humans continued to have sex during this period, such as Jack Harkness and Ianto Jones. (TV: Adrift)

Time Lords
By most accounts, Time Lords were implied to be capable of sexual procreation. The Master, for instance, claimed to have a father, (TV: The End of Time) as did the Doctor. (TV: Doctor Who, The Fires of Pompeii)

In several accounts, the Doctor explicitly referred to himself as having been a father himself prior to his tenth incarnation, (TV: Fear Her, The Doctor's Daughter, Listen) and was identified as the grandfather of Susan Foreman by Susan, (TV: "An Unearthly Child", "The Escape") Barbara Wright, (TV: "An Unearthly Child", "Hidden Danger") Ian Chesterton, (TV: "The Ambush", "Kidnap") Ping-Cho (TV: "The Wall of Lies") and the First Doctor. (TV: "The Brink of Disaster") Clara Oswald also referred to the Doctor's missing "children and grandchildren", (TV: Death in Heaven) while the First Doctor (TV: "The Rescue", Marco Polo, The Sensorites, "Flashpoint") and the First Elder (TV: "Hidden Danger") mentioned Susan as the Doctor's grandchild. In his eleventh incarnation, the Doctor recalled coming to the Rings of Akhaten "a long time ago with my granddaughter". (TV: The Rings of Akhaten)

Susan, too, had at least one child — whom she identified as the Doctor's great-grandson — by the human David Campbell. (AUDIO: An Earthly Child, et al.) The Tenth Doctor also described the possibility of genetically collateral relationships when he told Martha Jones he didn't have a brother "any more". (TV: Smith and Jones)

The Ninth Doctor once seemed distinctly perturbed when Rose Tyler implied he didn't "dance" — a metaphor for sex that had arisen between the two. (TV: The Doctor Dances) "900 years old, me. I've been around a bit. I think you can assume at some point I've "danced"."

- Ninth Doctor

However, another account suggested that sex had ceased to have a reproductive function on Gallifrey long before the Doctor's time. According to this school of thought, the "Pythia's Curse" had made Gallifreyans effectively sterile. Reproduction was carried out by the carefully controlled use of Looms, which produced new Time Lords as fully-formed adults. No direct genetic relationships were therefore possible. Time Lords arising from the same House — for each House had only one Loom — were considered "cousins". (PROSE: Lungbarrow)

The Doctor
Though rare, there were occasional hints that the Doctor did indeed have sex. Benny Summerfield and the Doctor might have had sex soon after he regenerated into his eighth body. (PROSE: The Dying Days) Summerfield seemed to confirm the incident when they met again at a later date. (AUDIO: Benny's Story)

"Dancing" was a euphemism for sex used by the Ninth Doctor and Rose Tyler. The Doctor said he had "danced" before and raised the question of who Jack would like to "dance" with: himself or Rose. (TV: The Doctor Dances)

The Tenth Doctor apparently had something of an eye for royal women, as he later had a brief marriage with Elizabeth I. After promising to be "right back" but fleeing her, (TV: The Day of the Doctor) he stopped just short of telling Ood Sigma that her nickname, "the Virgin Queen", was no longer accurate. (TV: The End of Time) Just after accidentally proposing to her, the Doctor quipped, "The Virgin Queen? So much for history." (TV: The Day of the Doctor) The Doctor's sexual involvement with Elizabeth I was later hinted at by future Queen Liz 10 (TV: The Beast Below) and by the Dream Lord. (TV: Amy's Choice)

The topic of sex was rather humorously referenced and unintentionally discussed between the Tenth Doctor and his companion, Donna Noble. When discussing the dangers of travelling with him, and with the Doctor admitting he just wanted a friend, he used the word "mate". Donna, being aware of the Doctor being an alien, completely misunderstood and took his use of the word as him wanting to have sex with her, which she vehemently refused to do. The matter was (mostly) resolved afterwards, but Donna was still rather put off at the idea of copulating with the Doctor. (TV: Partners in Crime)

Amy Pond, following a near-death experience with the Weeping Angels, attempted to seduce the Doctor's eleventh incarnation. Though he refused, he implied in answer to her question that he hadn't had sex in "a while". (TV: Flesh and Stone)
