PEOPLE WHO WORK IN HEALTHCARE, I NEED YOUR INPUT.

Long story short, I caught the Norovirus through a woman I take care of at work. That was Sunday and I was symptom free by Tuesday. Given that Norovirus basically lives in vomit and feces of an infected person and given that I have been symptom-free for about 3 days now, I was wondering how soon can I go back to have anal sex? I have regular vaginal sex on Wednesday, but I'm having a cow because my boyfriend wants anal, I want anal (and all its joy and foreplay) but I'm freaked that if he encounters my butt, he could catch what I had.

I'm not even sure its still inside me, I'm not sure how long it takes before it has completely run its course.

Anyone in the healthcare industry have this problem? No? Just me?
