What do you call someone with only technical knowledge of sex?
Virgin.
She's a gynecologist, so she has book knowledge.
She's a virgin, so no actual experience.
Sexless
Kyoko Omiya (大宮 杏子 Ōmiya Kyōko) Makoto's second cousin and an obstetrician and gynecologist. At the request of Makoto's mother, she moved in next door to the Onodas to encourage them to reproduce. A very dominant personality, she was still a virgin at age thirty, but she finally does get settled down with Koichiro Matsuzaki.
