Hmm. I think that posting this question on a sex toy site forum might skew your results more than a little bit since this community is comprised of people that have been drawn here out of their love of mastUrbation. I for one love it.
I'm pretty sure that no one on a site that sells vibrators, dildos and masturbation sleeves aplenty would indulge in such a sinful practice as masturbation. That would be just SINFUL. In all due seriousness, I'm sure there's not a person here who hasn't masturbated at least once, and indeed, likely most of the souls who waste time on these forums spend a great deal of time perfecting the art of self-pleasure. ^_^
