North is most noted for his ability to produce very large amounts of semen and for his powerful cum shots. He has averaged 8-10 ejaculations per climax since the start of his career in the porn industry over two decades ago. Female co-stars like Jenna Jameson confirm his volume of ejaculation to be real, with no movie trickery involved. Peter North has stated that his ejaculations have always been of a high volume and that he didn't know it was above the norm until he began his career in the porn industry. At the climax of sex scenes, North's ejaculations could last twenty seconds and upwards of a half minute.

North is circumcised, and is known for having an exceptionally large penis both in length and girth, as well as for consistently sporting remarkably turgid erections. The size of North's penis, reported to be 8.5 inches (21.5 cm) in length by 6 inches (15 cm) in girth, is amongst the largest of all current male porn stars. North has appeared in well over 1,000 pornographic movies.

Before working in hetero porn, however, Alden worked as a gay porn performer under the stage name "Matt Ramsey". He functioned as both a top and bottom during his gay career. In a famous scene, Rick Donovan topped Peter North in the 1984 film The Bigger, the Better . At this stage of his career, though, he does not acknowledge or discuss his gay porn performances. Whether he was gay for pay or not is irrelevant; his refusal to acknowledge this part of his career is factual.

He has also directed more than 70 movies (notably, his North Pole and Anal Addicts series), and produced over 20 movies, including 15 in the North Pole series.

North dated fellow porn actress Jewel De'Nyle for over two years.

In 1994, Peter North released a guide to meeting and dating beautiful women called Penetrating Insights. Its purpose is to help the reader meet more women. The book also includes tips on everything from grooming to personal health. He is well known for being in excellent physical shape, even as he enters his fifties. He is a workout buff.

North is a member of both the X-Rated Critics Organization (XRCO) and the Adult Video News (AVN) Hall of Fame.
