I have been in sexual activity, on surface with no penetration , I am a virgin.
well what confuses me that i had some confusion in my period for past two months ..after the i saw on my under wear.. like dark mucus .. i was not there after the activity .. what this could be , is it the start of my period or hymen?

It is normal because the interest over sex may also created this stage.
