Is it okay to have sex on the last day of your period?

Patient's question:

No

Doctor's answer:

Do not have sex during your period, as both partners become excited, and the insertion of the penis can cause the female reproductive organs to become engorged, leading to increased menstrual flow and prolonged periods. The male reproductive organs may introduce bacteria into the vagina, causing unnecessary trouble for the woman. Additionally, menstrual secretions entering the male urethra may also lead to the development of urethritis!
