My girlfriend and I are into male-orgasm denial. We've recently tried putting Orajel on my cock and then covering it with two condoms so she can use me as a dildo without me getting off or even feeling anything. It works great. Is there any chance of long-term health issues if we do this once a week or so?
My response after the jump...
You didn't say which kind of Orajel you are using, but I hope it's not Orajel Advanced Tooth Desensitizer. Its active ingredient—created to treat sensitive teeth, not desensitize cock—is something called "2-hydroxyethyl methacrylate," which sounds like something you might find in baby formula that was made in China. The stuff works, according to Orajel's website, "by blocking dentinal tubules, preventing excitation of the tooth nerve." And, hey, if it's safe enough for your mouth, it's probably safe enough for your cock and for newborns, right? Well, maybe not. A very quick search of the interwebs using that Googlemajob turns up a paper in the Journal of Dental Research with this rather alarming title: "2-Hydroxyethyl Methacrylate (HEMA) Is a Potent Inducer of Apoptotic Cell Death in Human and Mouse Cells."
Any responsible sex-advice professional would read the paper in its entirety and inform you about the likelihood that you're killing off cock cells when you smear them with Orajel Advanced Tooth Desensitizer. But I'm an alarmist sex-advice professional, not a responsible one, so I'm just going to lay that title on you one more time: "2-Hydroxyethyl Methacrylate (HEMA) Is a Potent Inducer of Apoptotic Cell Death in Human and Mouse Cells." I don't know about you, NDD, but I've always erred on the side of not smearing my dick with shit that kills mice. (Not all brands of Orajel contain this ingredient, but a boy can't be too careful.)
It seems particularly foolish to smear any kind of Orajel on your cock when there are products on the market specifically designed for desensitizing cocks, things like Mandelay gel and Proloonging's "penis desensitizing aid delay spray." These products are marketed to men who suffer from premature ejaculation, even though numbing the dick doesn't really cure premature ejaculation. They sound perfect for you and your orgasm-denying girlfriend.
