A few days ago my boyfriend accidentally introduced his penis in my back hole (which, by the way, hurt so much) and immediately got back to the vagina. Now, three days later, more or less, it itches a lot. I’m afraid of having a serious infection. What should I do?
Iâ€™m not sure from your question where youâ€™re itchy â€” in the anus or the vagina. The itching may or may not be associated with this particular act of intercourse. It might only be coincidental. So there are a few possibilities.
If the itch is in your anus, there are a few possible causes. The skin around your anus may have been split or torn when your boyfriendâ€™s penis entered it; you may have a hemorrhoid that was irritated; or you may have contracted an infection from your boyfriend. You should visit your health care provider for an examination and talk about what STI testing might be useful. (Most sexually transmitted infections do not become symptomatic in three days, so if the itching is caused by an STI, you may have had the infection for some time without knowing it.)
If the itch is in your vagina, it is possible that fecal material (bowel movement material) was passed from your anus to your vagina, which could cause an infection rather quickly. You should see your health care provider for an examination and to discuss whether STI testing might be appropriate.
Whenever partners switch from anal intercourse to vaginal intercourse, it is important to first wash the penis after anal intercourse and before starting vaginal intercourse. If condoms are being used, be sure to replace the one used for anal intercourse with a fresh condom before beginning vaginal intercourse. This is also true when using sex toys. If fresh condoms are not used for each act, the toy should be cleaned before use in a different part of the body â€” or on a different partner.
Fecal material should always be kept out of the area of the vaginal canal and the vulva (i.e. a womanâ€™s external sex organs, including the clitoris, the inner and outer labia, the opening to the vagina, the opening to the urethra, and two Bartholinâ€™s glands). Fecal material can cause infection of the vulva, vagina, and bladder. When people enjoy anal sex, or when accidents happen, it is always important to clean up any fecal material as quickly as possible.
Best wishes for your good sexual health,
