Scarleteen

I did not see any blood flow through my vagina when I first masterbate...at age 15.
Does this mean that my hymen was already broken when I first time had my period...
'cause I ride bicycle a lot and also play basket ball..
Could it have been broken at that time.. Also I did not experience any blood flow when I cycled or played..only during my period I face blood flow...
Please answer..

Hi Poorvi,

So, what most people think of as the hymen is actually something called the vaginal corona. You can read all about it here: My Corona: The Anatomy Formerly Known as the Hymen & the Myths That Surround It

An important point is that you're not "supposed" to bleed as a result of your first masturbation or first intercourse. Many people do bleed due to being tense or under-lubricated, but that doesn't make their body's response more correct than someone who does not bleed.
