Yes, it is possible for a couple to get chlamydia without cheating. Chlamydia is a sexually transmitted infection that can be spread through unprotected vaginal, anal, or oral sex with someone who has the infection. However, it can also be transmitted through non-sexual means such as sharing sex toys or coming into contact with infected bodily fluids. It is also possible for someone to have chlamydia without showing any symptoms, which can make it difficult to know who may have transmitted the infection. So even if a couple is in a committed relationship and both partners are faithful to each other, they can still contract chlamydia if one partner has been exposed to the infection through other means or from a previous sexual partner. It’s important for couples to discuss their sexual health and get tested regularly for sexually transmitted infections, regardless of whether or not they suspect infidelity.
