Better, since she won't be too shy to ask Minako and Ami for advice. Mina watches too many dirty movies(and probably has a few notches in her headboard by the time Chibi-Usa comes asking), and Ami is more in the literary side of things, and has a copy of the Kama Sutra tucked away in her personal library.

Hotaru is her age, doesn't have any more experience than she does.
Setsuna is a perma virgin unless she decided she's going to hunt shotas.
