The CIS has conducted a study on sexuality in which citizens are asked about their habits, opinions and customs in relation to this subject, about sex robots and assisted human reproduction, among other aspects. Romantic relationships 73.5% of those surveyed agree that having a romantic relationship is important for a satisfying life, compared to 23% who think it is not. Furthermore, 84.8% consider living together in the same house within a romantic relationship to be "very or quite important," and only 13.5% believe that living together is "not very or not at all important." Likewise, 85.5% consider economic independence in a romantic relationship to be "very or quite important", compared to 12.8% who say it is not. 50 years ago… 78.8% agree that affective and sexual relationships “are more unstable than before”, 61.8% believe that relationships now “generate more uncertainties” compared to 50 years ago and 73.3% state that relationships today “have been profoundly transformed by social networks and the Internet”. On the other hand, Spaniards believe that relationships today allow for greater individual freedom (81.6%), are more equal between men and women (75.6%) and are more pleasurable than 50 years ago (64.2%). 69.2% of citizens acknowledge having a partner, and of those, 97.4% state they are in a relationship with only one person. Only 1.2% of those surveyed who have a partner claim to have “an open relationship, with sexual relations outside the relationship.” Among those who claim to be in a romantic relationship but do not live together, 61.7% "do not rule out living together in the future", 23.8% say that "it is a long-distance relationship, but they do not rule out living together in the future" and 6.4% "have decided that they will not live together". The 'unmarried' Among those who claim to be single, 22.3% say they "have casual relationships, non-exclusive dates" compared to 73.4% who say they have "neither relationships nor dates". 36.6% say that in 5 years they want to continue living "without relationships or a partner", while 20.5% would like "to have a stable relationship, to live together without being married" and 17.5% prefer "to have a stable relationship, but each living in their own house". Sexual relations 75.1% of those surveyed acknowledge having had sexual relations with their partner or other people in the last 12 months, while 24.6% have not. Among those who have not had sexual relations in the last year, 16.3% attribute it to "lack of interest or sexual desire", 13.5% "widowhood" and 11.2% "illness of their own or their partner". Regarding sexual experiences, only 12.9% acknowledge having had “open or non-exclusive relationships” at some point, 7.9% claim to have engaged in “domination or submission practices”, 6.8% in “specific fetishes”, 5.2% in “polyamory”, and 4.7% have participated in “orgies”. Among those who have engaged in open relationships, 42.8% acknowledge that it "was a phase in their lives" and 29% "a one-off experience." Of those who have engaged in dominance or submission practices, 42.2% state that it was "a one-off experience" and 26.1% say that it "is a regular part of their sex life." Of those who have had specific fetishes during sex, 40.7% describe them as a "one-off experience", while 30.2% say it is a "regular part of their sex life". Regarding this type of sexual practice, 26.3% consider themselves "neither open nor conservative", 25.4% "rather conservative", 18.6% "very conservative" and only 26% "very or quite open". Erotic toys 58.5% of Spaniards admit to having used erotic products such as sex toys, lubricants, oils or other objects to stimulate pleasure, compared to 41.3% who admit to not using them. Among those who admit to using them, oils, lubricants and other erotic cosmetics are the most used (92.9%), followed by sex toys (75.8%) and, in third place, erotic clothing, lingerie or accessories (61%). The majority of respondents indicate that they have used them with a stable partner; for example, 85.4% say they have used lingerie or erotic accessories with their partner, 70.7% have used oils, lubricants or erotic cosmetics, and 57.4% acknowledge that they have used "other objects not intended for pleasure" with their partners during sex. Among those who have ever used an erotic product, 33.9% admit that they did so out of "curiosity or experimentation", 26.1% to "improve sexual satisfaction", and 23.8% for "fun". Robots for sexual purposes 80.6% say they would never be willing to have sex with robots, 13.9% consider it “unlikely” to have such an experience, and only 4.4% say it is “very or quite likely”. 18.7% strongly or somewhat agree that knowing your partner uses sex toys alone creates pressure in sexual relationships, while 75.5% strongly or somewhat disagree. Furthermore, 56.7% strongly or somewhat agree that using sex toys enriches sex life, compared to 37% who disagree. Assisted reproduction The most well-known assisted reproductive technologies are artificial insemination (89.8%), egg or sperm freezing (88.3%), and in vitro fertilization (86.8%). All of these are widely accepted among the Spanish population. These and other data are collected in the study 'Sexuality: habits and opinions' carried out from March 5 to 12 with 4,009 interviews.
