Age doesn't matter lol.

So if your hymen is still at hand (you could have broke it by intense physical go or such) it might hurt. The pain will second until the penis breaks the hymen (the hymen is a small and thin piece of tissue, sort of close to skin, on the entrance to the vagina). BUT if you're aroused enough, probability are that the soreness will not exist at all. You might bleed after the hymen is broke, so you could use a panty liner to prevent stains on your clothes afterwards.
