How could you get it?

How could a person who is in a monogamous relationship be positive for an STD if it's the first sexual encounter he/she had, and if the other partner has been tested negative?

What std are we talking about?

Someone must be lying.  Chlamydia is only transferred through sexual contact.  It is possible to get Chlamydia through oral sex if the girl is giving oral sex to a male who has chlamydia.

Is it possible for a guy to get chlamydia from the girl through oral sex?

[jrbell]

Chlamydia is unlikely to spread through contact with saliva and is even less likely to be spread through oral sex, either active or passive, when compared to vaginal or anal intercourse. Transmission from mouth-to-penis or penis-to-mouth is unlikely, but possible. The infection is even less likely to be transmitted from vagina or anus to mouth. Furthermore, oral sex is not known to pass the bacteria from mouth to vagina or anus.

To answer your question directly, it is possible for a guy to get chlamydia from a girl who has it through oral sex, but the chances are really low.

I agree.  Either someone had a false test result, or someone is lying.

Or your partner brought it into the relationship.  It just depends on how long you've been together.
