If you are reading this to help a partner have a good first time: Your job is to be patient. Do not look for blood to “prove” her virginity. Do not get frustrated if it doesn't fit. Do not ask, "Did I pop it?" (The hymen does not "pop.") Instead, ask, "How does this feel?" and "Do you want to keep going?" Your gentleness today will define her desire for sex for years to come.
