Within Thedas, there are several different views in regards to sexuality and marriage. Common to all groups is that marriage is not primarily regarded as a romantic affair, but a duty to one’s family.
Viewpoints
The Chantry
According to the Chant of Light, Andraste had a spiritual marriage with the Maker. All Andrastian priests are symbolically wedded to the Maker; they cannot marry, but are not required to be celibate. In the eyes of the Chantry, marriage is a matter of tradition and practicality, and a holy bond between man and woman. Love is not necessary, but love within marriage is the ideal. Other than that, the Chantry has few regulations regarding sexuality.
The Chantry does not have divorce, but a marriage can be annulled.
City Elves
Among city elves, marriage is what distinguishes children from adults. Usually, elven children are betrothed according to the consent of their parents and the Alienage elders, and often the bride and groom will not have met each other before the marriage ceremony. Betrothals often involve families from different Alienages, in order to promote inter-city trade and relations, as well as to bring new elves into the tight-knit Alienage community. Marriage ceremonies require the approval of the Chantry, and are officiated by one of the Chantry priests. In a community where there is mostly little cause for celebration, a wedding is a tremendous affair, and friends and relatives come to enjoy the feasting and dancing.
Dwarves of Orzammar
The dwarves of Orzammar have one of the most sensuous cultures in Thedas. Polyamory (having multiple intimate relationships) is common, and brothels are legal. While a dwarf has only one wife or husband, many nobles keep concubines, who are considered part of the household and have their names recorded in the Memories. A dwarf’s caste is determined by that of their same-sex parent, so many lower caste men and women offer themselves to nobles in the hopes of a producing a child of the noble’s gender. As dwarven fertility is in dangerous decline, any noble child is considered a blessing, and a lower caste dwarf who is suitably fertile will be taken in to the noble’s household as a concubine. Frequently, if the initial liaison with a noble produces a child of the lower caste dwarf’s gender, the infant will be disposed of, as they would be an embarrassment to the noble parent and any noble siblings to follow.
Grey Wardens
Although Grey Wardens are not forbidden from marrying, it is rare for them to do so. Their short lifespans make them poor candidates for parenthood or long-term relationships. Even if they are not killed in battle against the Darkspawn, they rarely survive past middle age due to the Darkspawn taint. Most Grey Wardens dedicate their brief lives to fulfilling their duty, leaving them little time for pursuits such as family life. Furthermore, the taint makes conceiving a child very difficult (nearly impossible if both partners are Grey Wardens).
Mages
Mages, because of their outsider status, are not bound to traditional social mores and consequently enjoy greater sexual freedom than most. They are discouraged from marrying and reproducing, as the offspring of mages are very likely to possess magical ability themselves. Dialogue between Wynne and Alistair hints at some form of birth control or abortion being readily available to mages, perhaps to discourage the propagation of magically gifted children. If a mage does produce a child, it is taken from the parents at birth and raised under the supervision of the Chantry. Those children who prove to have magical ability are immediately transferred to the Circle, where they are held in complete isolation and taught to control their powers. Mages who do not wish to be separated from their children will sometimes conceal them from the Chantry and either train the child themselves or hire an apostate as a tutor (as with Connor and Isolde).
Orlais
Aristocrats in Orlais like to outdo each other when it comes to showing off their extravagant tastes, sexual or otherwise. The peasantry is much less tolerant of such things, at least in public. According to The Stolen Throne, the ruler of Ferelden during the Orlesian occupation, Meghren, reputedly had sexual relations with his cousin Florian, the Emperor. There was perhaps some scandal involved that led to Meghren being "banished" from Orlais to be King of Ferelden, but this may be more a result of the fact that Florian was Meghren's cousin rather than the nature of the relationship itself.
Qunari
The attitudes of the qunari towards sex and marriage are unknown. Qunari women have only rarely been observed by outsiders, and other races find it difficult to believe the stoic qunari capable of any personal relationships.
Homosexuality
Same-sex relations are generally considered odd but not immoral in Ferelden. Orlesians regard it as a mere quirk of character, and the Antivan Crows show a winking tolerance for (if not encouragement of) relations with multiple partners of either sex. There is pressure in certain circles, such as the City Elves and the human nobility, to marry an opposite-gendered partner in certain circles, but this is motivated by pragmatism rather than morality; a homosexual couple cannot have biological children.
Interspecies
The children of elves and humans are always human. As the elves are a dying race, there is a great deal of pressure for each member to produce children. Relationships with humans are considered traitorous and anyone who has a child with a human may be kicked out of the community.
Dwarves have difficulty reproducing and many dwarves consider humans and elves lesser races. For this reason, they are also against interspecies relations. Humans and dwarves can produce half-dwarves, but this is very rare.
Prostitution
Brothels are legal in Ferelden and in the Dwarven city of Orzammar. While it is not particularly respectable to visit a brothel, it is not considered a big matter.
