How Safe Is It To Share Earbuds?

Am I the only one who thinks that it's not OK to share headphones? Especially earbuds. I'm not sure why, but I am just not a fan of sharing my earbuds with anyone!

Sharing earbuds is similar to shaking hands or kissing. If you or your friend have an ear infection (symptoms include: pain and a tick, yellow drainage), the bacteria can be transferred via earwax, says Marc Error, M.D., an ear, nose and throat doctor.

So if you do not feel like sharing more than just music, keep your buds to yourself. Ears in the clear? then jam out together. (Women's Health)

Are you OK with sharing your headphones with someone? Am I just being a freak or is sharing earbuds a no-no with you as well?
