The bisexual community has had a growing presence in the Bay Area since the mid-sixties. Out bisexuals within the Sexual Freedom League; National Sex Forum; San Francisco Sex Information; the Institute for the Advanced Study of Human Sexuality; the Radical Therapy Collective; the Gay Liberation Front; and the Peace, Civil Rights and Women's movements built the foundations upon which the Bay Area Bisexual Network (BABN), BiPOL, Bi-Friendly; and BiNet USA now stand.
