How you as a gynecologist know if a guy had anal before?

As a gynecologist, I don't assess sexual history based on physical examination alone, as it can be difficult to determine specific sexual practices without clear communication from the patient. Signs of potential anal intercourse may include specific physical findings, but these are not definitive. It is essential to create a safe and non-judgmental environment for patients to discuss their sexual history openly and honestly. Ultimately, thorough communication is key to understanding a patient's sexual health.
