My husband and I tried anal and he slipped out into my vag, 2days cheesy/smell/itch, now just itch/?

Same question/answer. This must be quite upsetting to you. It may be a simple yeast infection by the symptoms that you describe. It is reasonable to try an over the counter vaginal anti-yeast product, but also get an exam with your physician quickly, for a look and cultures to be safe. There are patients with recto-vaginal connections, and they do get different kinds of infections due to stool leaking to the vagina.
