Actually in the colonial days, many local wealthy businessmen
kept very young virgin mistresses not for sex, but for extract the
"chi" from inside these young virgins.
It was believed that putting small cherries inside the virgin and
will result in the cherries absorbing the "chi" energy from the
virgin; especially when the virgin is aroused without being
satisfied.
The cherries are kept for about 24 hours in the virgin, removed and
soaked in wine jars, with fresh cherries replacing the "energised"
cherries that have been removed from the virgin.
The wine and cherries are drunk and eaten, with the "chi"
supposedly revitalising the man.
However, it is a cruel act, as the poor virgin will age faster and
is supposedly weaken in the process.
The man who consume too much of the feminine "chi" may result in
becoming effeminated as a result of overdose.
So retribution does exist.
