your boyfriend may be not be telling the truth. chlamydia is caused by exposure to someone else that has chlamydia. simple as that. going from anal to vaginal sex can cause a severe bacterial infection from pathogens that live in the colon. this is not a safe sexual practice. both you and your boyfriend need to be carefully tested since chlamydia is often accompanied by other stds. word to the wise: use condoms with this guy. and other guys too.
can you get chlamydia just from switching from anal sex to vaginal sex? . i just found out that i have chlamydia i've been with my boyfriend for two years now a couple of months ago we had anal and switch to vaginal sex could that be the reason why i have chlamydia? i confront him about it but he said that he hasn't been with anyone else but me and he's making an appointment to get himself check.
