What is Xtubate?
Masturbation to user-generated pornographic videos, viewable on web sites such as xtube. Unlike offline or partnered masturbation, which is often begun intentionally with the goal of a relatively quick orgasm, xtubation is generally begun unintentionally, or as an escalation of online voyeurism. Many xtubators attempt to delay orgasm until they find a video worth serving as a final destination.
I had no intention to xtubate last night, but before I knew it, I had spent an hour xtubating to my friend's favorite videos, and now my mousepad smells funny.
