is self-stimulation during your period good?

This is not a matter of good or bad this is unhygienic and messy, your period i there to clean your self the natural way, this is the time when nature make sure your male sex partner will get rest to produce enough sperm as well for you to clean yourself inside. So do not interfere with mother nature.

The best way when you are on your period is to do it when you are in the shower. I get very turned on around my period and I have to do it to relieve some of the tension.
