If 2 people who don't have any STDs have sex, it's not possible for either of them to get one. A couple can't create an STD from nothing — they have to get spread from one person to another.
It's quite another to learn you have an STI while you're in a monogamous relationship. If you have been totally faithful, you may assume that your partner acquired the infection while being unfaithful. Though it's possible they may have been intimate with someone else, it's also possible they never cheated at all.
Although chlamydia is highly contagious, it does not always transmit to a person's sexual partners. It is also possible to have a false-negative test result. Having more frequent sex with a partner who has chlamydia may increase a person's risk of contracting it.
How did I get chlamydia if I didn't cheat? You can get chlamydia if your partner had vaginal, oral or anal sex with someone who was infected and then had sex with you.
How is chlamydia spread? You can get chlamydia by having vaginal, anal, or oral sex with someone who has chlamydia. Also, you can still get chlamydia even if your sex partner does not ejaculate (cum). A pregnant person with chlamydia can give the infection to their baby during childbirth.
It's important to know that chlamydia is not transmitted through casual contact (kissing or hugging, sharing food or drinks, or from toilet seats). The only way for chlamydia to be passed between people, apart from sexual contact, is from a pregnant person to their baby during childbirth.
It's not very likely, but it's not impossible. The chances are a lot lower than they are for people who have had sex with other people. But it is possible for two people who've never had any kind of sex with anyone else to get a sexually transmitted infection by having oral sex.
As most people do not have symptoms, it is possible the person (who tested positive) could have had chlamydia/gonorrhea from a previous relationship, and has not passed it to their partner yet. It is never 100% that you will pass an STI when you have sex.
Can you develop a chlamydia infection on your own? Fortunately, you can't contract chlamydia on your own because it spreads through sexual contact with other people. Chlamydia bacteria does, however, thrive in vaginal fluid, semen, and pre-ejaculate (the fluids that the penis may release before sexual climax).
Only Three STIs Are Transmitted Sexually Every Time
That may be the case, of course, but it's also possible to contract several STIs without infidelity, and in some cases, without any sexual contact. Only three STIs are transmitted exclusively sexually: gonorrhea, syphilis, and genital warts.
Symptoms can occur within 2-14 days after infection. However, a person may have chlamydia for months, or even years, without knowing it.
A couple can't create an STD from nothing — they have to get spread from one person to another. But just because someone hasn't had any genital-to-genital contact with anyone else doesn't necessarily mean they don't have an STD.
Chlamydia is more common in young people, especially young women. You are more likely to get infected with chlamydia if you don't consistently use a condom or if you have multiple partners.
Symptoms in men
pain when urinating. white, cloudy or watery discharge from the tip of the penis. burning or itching in the urethra (the tube that carries urine out of the body)
Apart from being infected at birth you can not catch chlamydia without performing some form of sexual act. However, you don't have to have penetrative sex to get infected, it is enough if your genitals come in contact with an infected person's sexual fluids (for example if your genitals touch).
Chlamydia. Symptoms usually appear after 1 to 3 weeks but can start much later. Symptoms include: discharge from the vagina or penis.
Although some symptoms can appear within weeks of contact, there have been reports of chlamydia remaining dormant for over twenty years. If you have had recent sexual contact and wonder about chlamydia infections, don't hesitate to test.
False-positive Chlamydiazyme results during urine sediment analysis due to bacterial urinary tract infections.
The concern with false positives drops as prevalence increases; the same test in a population with 10% prevalence of chlamydia has a positive predictive value of 87.8%, so only roughly 1 in 10 positive results would be a false positive.
If a UTI is left untreated, it can turn into a kidney infection – which is much more serious and difficult to treat. But no, UTIs will not cause chlamydia or any other STD. Because UTIs are often caused by the mechanics of sex (bacteria moving around the genital area), peeing before and after sex can help prevent them.
How do people get chlamydia? Chlamydia spreads through vaginal, anal, or oral sex with someone with the infection. Semen does not have to be present to get or spread the infection. Pregnant people can give chlamydia to their baby during childbirth.
Myth: You can't catch chlamydia if you've only had sex once. Fact: If you have sex once with a partner who's got chlamydia, you've got around a 30% chance that you'll pick up the infection from that one time.
Chlamydia. A doctor can test for chlamydia by swabbing the vagina, cervix, rectum, or throat, or by taking a urine sample. If symptoms appear, they usually present within 7–21 days of exposure. A test can normally detect chlamydia within 1–2 weeks of exposure.
