K-Hole (2003)

Dean is a wreck of a man trapped in an abyss of drugs and unsafe sex, living his life with little concern for himself or others. Teetering on the edge, hardly anything or anyone can affect Dean’s lifestyle except the need for more drugs. Though proclaiming himself “straight” Dean is willing to do just about anything to satisfy his urges, including participating in orgies and gay sex in the back of a car. Other characters include Dean's neighbor Ellsworth who barters Ketamine (special K) for sex, Brioni who throws a party/orgy and Cyja - Dean's ex-girlfriend and drug counselor.

Unfortunately the movie K-Hole is not yet available on HBO Max.
