Doctors in Sweden have been dishing out free measuring tapes to help young men buy the right size condoms.
A health clinic in Stockholm is on a mission to encourage safe sex and has been handing out tapes, which have been specifically designed to measure manhood girth, to ensure they buy a size that will best fit their penis.
Eddie Sandstrom, a male nurse at the clinic, said: "A common reason for a condom slipping off or breaking during sex is that you've bought the wrong size.
"You have to measure the circumference of the penis when erect, not the length. On our measuring tape you get the measurement in millimetres and a few recommendations for condom types that are suitable."
