A big part of all Inhabited Land is used for sexual activities. The Linden official position is that in General sims, explicit adult content is forbidden, in Moderate places adult content is allowed only behind closed doors, while in Adult sims, there are no restrictions.As seen on Gridsurvey, 'Adult' places are increasing in number, with a direct result of increasing sex-related places.Under this name are known lesbians, gay people, bisexuals and transsexuals.For other Linden-owned continents, except Sharp Continent which is 'General', land used for sex is between 1 and 3% of all land and between 2 and 5% of all Inhabited Land.The most accurate data is found on private-owned land.They have plenty of areas to hangout, to sail, to flirt and to have an intimate life.
