because for me and my bf
we have sex
and one day
after we really had sex
he told me he thinks his penis become longer
and i didn't believe it
so the next day
we did it again
but finally

he grew is because when we had sex , we keep moving, and it broke one part of the skin on the penis, so the penis has more space to grow
