I just came across an article on AskMen.com that had me do a double-take. The article is two pages of tips on how to endure a sex marathon! The author advises the reader not to orgasm, to pleasure his partner in order to keep the focus off himself, not to drink too much, to get creative, to keep lube handy, and to have a glass of water handy.
While I'm all for an extended romp every now and again, a sex-a-thon doesn't interest me in the slightest. Does it you? Would you be interested in taking all these precautions if it meant sex for hours on end, if not all night, with your special someone?
