Patient's question:

Patient Gender: Female
Patient Age: 36
What medication is best to take during sex? I am 21 and it has no side effects on my body.

Doctor's answer:

Hello, do you want something that lasts longer? The best-selling product right now is Viagra! Most pharmacies have it, so you can give it a try. However, don't consume too much of this stuff. As everyone knows, prostatitis can cause significant harm to patients, so it's important to seek treatment as soon as possible. In daily life, pay attention to dietary issues—stick to a light diet and avoid foods. Additionally, you can schedule regular follow-up appointments when necessary.
