Block is also a self-proclaimed sex therapist in private practice and works with clients from all over the world, using her therapy techniques to deal with various sexual problems, both in person and over the telephone.

[10][11] In the late 1970s and early 1980s, Block continued her studies in theater, sex and philosophy at PWU, San Francisco State, UC Berkeley, and the Naropa Institute.

She also traveled extensively throughout the United States, Mexico, France, the Netherlands, Italy, Israel, Afghanistan, Pakistan, India and Nepal.

[citation needed] In 1984, Block published her first book, Advertising for Love[13] (William Morrow) which forecast the personal ad revolution that soon began in newspapers and magazines and now, the Internet.

In 1996, after the owners of IBN were indicted for fraud, Block started one of the Internet's first radio stations, RADIOSUZY1.com, where her show is still broadcast, live and taped, 24 hours a day.

That year, she also hosted her first HBO special, Radio Sex TV with Dr. Susan Block, and published her third book The 10 Commandments of Pleasure: Erotic Keys to a Healthy, Sexual Life (St. Martin's Press).

In 1998, BlockFilms began producing the Encyclopedia of Sex & Fetish series, including "The New Horny Housewife", "Feet: An Erotic Study in Podophilic Sexuality", "Kenneth W. Starr: A Pornographer for Our Times", "Vibrators & other lovers", "The Fine Art of Fellatio", "Luscious Cunnilingus", "Sex Heals" and "Spanking for Adults Only,".

Around this time, Block became a consultant for the Los Angeles Public Defender's Office, Death Penalty Sex Crimes Division.

Also, in 1998, she moved her institute and production company from the "Villa Piacere" in the Hollywood Hills to "Dr. Suzy's Speakeasy" in Downtown LA.

A year later, Block, acting in pro per, sued the LAPD for infringement of her First and Fourth Amendment rights, and won a settlement.

Also in 2000, Block started fighting a public Freedom of Speech battle with Adelphia CEO John Rigas who censored the nudity on her Public-access television show.

The Dr. Susan Block Show continues to broadcast without censorship on BTV, where it is produced by First Amendment advocate and artist Frank Moore.

Dr. John Perry, author of the best-seller The G-Spot, calls Dr. Suzy's Squirt Salon "Masterful...raising the bar for female ejaculation videos".

Cara Jepsen put it this way in the Illinois Entertainer: "Dr. Susan Block's HBO specials expose inhibited Middle America to the idea that it's OK to discuss—and enjoy—sex..."
