To answer that question, the goddess kissed you on the lips, which caused you to blush. Why would the goddess do this when she was a thousand years older than you, as if she was trying to explain something. The goddess stops kissing you, and got back up off the bed feeling like you haven't done it before.
"What?" Ceridwen asks. "You're acting like this was your first kiss?" "That's because it was," You answer. "Aren't you worried about losing your powers if you kiss a mortal boy like myself?" "Well incest was banned for Gods, and Goddesses in the 40s, when Zeus stopped doing it with his own family," Ceridwen explains. "Therefore, it became legal for Gods, or Goddesses to date mortals. You, and I will be having fun on Christmas Eve this Saturday. Be prepared, because it'll be very fun."
