Ask Grand Pa or Grand Ma or those who live through the early
colonial days; it is doubtful if mummy and daddy will know.
Have you not heard of some well known spinster in Malacca, who
maintain her youthful energy by paying for the services of young
body building males?
She do not use their service directly to satisfy her physical
needs, but "milk" the young men's energy, and consume every drop of
it, and as much of it every day for the duration of the
arrangement.
The poor young man was deluded by lusts and money, and will soon be
a shrivel of his original muscular hulk.
Go ask Grand Pa or Grand Ma - it will be a challenge in itself how
you pose the question.
