I am a celibate, adult woman. I don’t have an with the male and female deities, but I am very uncomfortable with the goddess being defined as pre-sexual, sexual, and post-sexual when I am none of these things (I am not asexual, but choose celibacy because it allows me to lead a lifestyle that suits me). I am more like Artemis or Athena that the “Earth Mother”.
