Three Reasons it's Dangerous to Share a Razor With Your Sexual Partners

Couples share a lot of things. They share interests. They share kisses. They occasionally share meals off the same plate. Sometimes they share colds or other diseases, including sexually transmitted ones. A subsection of couples also share personal hygiene products, like toothbrushes or razors. Here are five reasons why sharing a razor with your partner may be a worse idea than you think.

Note: You shouldn't share toothbrushes either, but I'll leave that explanation to another Expert

Blood to Blood isn't Skin to Skin

I wanted to write this article, because I was talking to a friend who shares his razor with his girlfriend. When I expressed that this might not be the best choice, he said, "But I rub all my bits against her bits all the time!"

True enough, I suppose, but there is a difference between skin-to-skin contact, which is risky enough in its own way, and blood-to-blood contact. The second not only makes it easier to pass on bloodborne illnesses, it may also make people more susceptible to serious skin infections. Broken skin is a lot easier to infect than intact skin, even if the tears are only microscopic.

Oddly enough that's something many people don't think about. So they'll share razors and toothbrushes, even when they're not fluid bonded.

Sharing Razors is a Known Risk Factor for Hepatitis C

Scientists haven't looked at the risk of sharing razors in too many contexts, since it's pretty clear that it's a bad idea. However, they have shown that sharing razors is a risk factor for hepatitis C.

It's also been shown that used razors can carry hepatitis B, although there's less clear evidence of transmission there. That may be, in part, because hepatitis B is preventable through vaccination.

Note: Toothbrushes can also be contaminated with Hepatitis C, since brushing teeth can lead to bleeding.

Razors Can Disrupt Skin Lesions

Diseases that are spread from skin-to-skin, such as molluscum contagiosum or herpes, can be spread across a person's own skin by shaving. The scraping of the razor disrupts the sores and moves around the pathogen to skin it has not yet had a chance to infect.

That works between people as well, at least in theory. If your partner's razor is contaminated with infectious particles, sharing it is probably a great way to inoculate yourself. Not only might the razor have made your partner more infectious, by breaking open sores, it might make you easier to infect -- by scraping up your skin.
