Okay so I dont know if this is true, but I heard that if you masterbate while you are on your period you will be done your period that week earlier than you usually are. Is that true?
Orgasms and the moments leading up to them produce contractions. These contractions force out the dead material faster. Just from personal experience with my love, yes, it will. A few good orgasms should be able to reduce it by a day or two, depending on how heavy your period is. But don't take me word for word on it. It's not an exact science.
No, it wont... but like the above said it can help whit pain... but it is going to look a little messy...
GOOD LUCK:)
No, it's not true at all. Masturbation could however help for period cramps.
