Chlamydial (pronounced "klam-idd-ee-al") infections occur fairly frequently in Europe. The tiny bacteria responsible are named Chlamydia trachomatis. They multiply in mucous membranes: in the urethra (the tube through which urine passes out of the body), the vagina (more precisely, in the mouth of the uterus), in the bowel and in the throat. To become infected, your mucous membrane must come in contact with an infected mucous membrane or with an infected body fluid. This comes about most often through fucking and blowjobs.

You often don't notice it when you've been infected with chlamydia. Sometimes it causes inflammation, for instance in the urethra, the epididymis (inside parts of your balls) and in the bowel. If you get a burning sensation or pain when peeing, or if you notice some discharge, you should definitely get yourself examined for chlamydia. It's a much more common infection than the clap (gonorrhoea). There's a special antibiotic that treats the infection very effectively. And you really should get treatment because even if a chlamydial infection is not much more than a nuisance to you, it can lead to infertility in women.

Condoms and the female condom provide good protection.
