If i have oral chlamydia, could it spread to my genitalia?

First, despite what some online sources may say, oral chlamydia is rare; when present, the body's immune system clears it within a week or two; it is not transmitted by oral sex or kissing; and no oral STIs ever are transmitted to one's own genital area. You'll never have genital chlamydia until and unless your penis penetrates another person's vagina or rectum (but not mouth).
