Can your doctor tell when you last had sex?
She might be able to if it was the last thing you did before leaving home, says Lauren Streicher, MD, assistant professor of obstetrics and gynecology Northwestern University's Feinberg School of Medicine. The evidence may remain inside you for 12 hours. This presents a bit of a challenge, says Streicher, because ejaculatory fluid-as well as spermicide, lubricants and creams-alter the vaginal flora (we love that phrase) in ways that can make it difficult for your doctor to accurately read your test results. If you're getting a Pap smear, give your doctor a heads-up about your very recent tryst so that she knows what she's dealing with. If the reason for your visit has to do with abnormal discharge or odor, abstain from sex for about 12 hours, or consider rescheduling. But good news if you're feeling self-conscious about a monthslong dry spell: Your doctor won't be able to tell unless you decide to tell her, says Streicher.
