At first I was resistant to the word addict, but upon further reflection: While I believe I have my impulses–sexual and otherwise–under pretty firm control, it was not ever thus in my history as an Onanist. Readers of my posts will know what I mean. During my adolescent years and into my twenties, I had a masturbatory monkey on my back, which (along with the show-off and peeker part of my personality) drove me to occasional escapades of high risk (public nudity and masturbation) and high excitement. Looked at objectively, one might see addiction in that behavior–the need to jack off could build to a point that my better judgement was overwhelmed by the urgent need to stoke my cock and shoot my load, even in places and at times where it could have meant real trouble.So in my hormonal youth, I might well have been called an Addicted Masturbator; but in my later, more mature years, I think the term I have used before is more fitting: Masturbationist. Pumping my hard, slippery dick for hours until I cover myself in hot spunk is may favorite leisure activity, my cherished hobby, a lifelong source of happiness.
