She founded Down There Press, a publisher of sex-related books, in 1975. In 1977, she opened Good Vibrations, the second feminist sex toy business in the United States (the first having been Eve's Garden in New York City, which was founded by Dell Williams in 1974). She was one of the first volunteers at San Francisco Sex Information and has served on the Board of Directors of the Society for the Scientific Study of Sexuality. Blank is also known for her inventions of the Butterfly vibrator and Titattoos (now Intimate Art Tattoos).
Blank has one daughter, Amika, and three grandchildren. She lives in Swan's Market Cohousing in Oakland, California, where she volunteers her time to social justice issues such as prison reform and economic equality, the Cohousing Association of the United States. She remains active in the field of sexuality, and many of her old books and videos are available through her Web site.
