Dr. Caron's Response:

Let me begin by stating that just because something is not common does not mean it is not normal. And although we usually think of masturbation as a solo activity, it can be shared with a sexual partner in person, or via phone or internet. It also happens in groups. Please keep in mind that finding good research data on masturbation is difficult because many people are not comfortable reporting honestly about their masturbatory behavior. Having said that, when looking for data on straight males masturbating with other straight males, it does not appear to be a very common practice - at least in the published research arena. The little research found on this would fall into the category of group masturbation - also known as the "circle jerk" - where groups of boys form a circle and see who can masturbate the fastest or propel their ejaculate the furthest. One recent paper on this very topic was published by Cornog in the Journal of Sex Education and Therapy. An adult version of group masturbation occurs in organized clubs, sometimes referred to as Jack-Off or JO clubs. One example is the New York Jacks, a male masturbation club started in the 1980s. Although it is thought that this type of shared masturbatory experience most likely occurs between gay males, we know it also includes women and heterosexuals. This is seen in the rise in clubs now referred to as Jack and Jill Off or JJO clubs. Getting back to your question - I think it is important for the people participating to decide what they are comfortable with - and if this feels right for them - in terms of their own values and beliefs. That's something to consider when deciding whether to share this side of oneself with another person.
