These are some stories that I've collected over the years that focus on the male chronic masturbator experience. There are true and candid personal histories, essays, fantasies, and porn fiction. The sexual orientation varies from hetero to gay, but always focusing on the male as masturbator.
For stories featuring male masturbation in a female context, see Guided Masturbation Stories
And also see the support group for chronic masturbators, OnaniaSupport : Living with Masturbation Addiction and the blog ONANIA -- The Journal of Chronic Masturbation
I've included author and provenance where possible. They very quite a lot in tone and subject.
