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 will cause the female reproductive organs to become congested, 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!
