This can happen because of the sudden increase in blood pressure, muscle tension, or changes in hormones during the activity. To help lessen these headaches, you might try taking it slower, using techniques to relax, or turning your body to a different position. If the headaches still annoy you, it's a good idea to talk about this with a doctor.

Having sexual intercourse with an HIV-infected partner without condoms is risky and may result in HIV infection. If you have had sexual intercourse with a sex worker and the condom has torn, you should test for HIV as well as other STIs as soon as possible. 

Quite often, a person will irritate a temporary malfunctioning of the excretory system due to too frequent or too expressive self-fondling.
