Anyway the tuition fees in NUS, NTU and SMU are increasing so
much and making the students more desperate... Maybe someone should
tell the uni about this prostitution issue, and discourage the uni
to raise tuition fees again... 
By the way in other countries, not only uni gals sell themselves...
Uni guys also sell themselves!!! They become "male escorts", "pet
lovers" for wealthy women or gay men, male prostitutes (known as
"ducks" in China), porn actors, models for gay magazine, etc. Many
of these guys are actually not gay. They are straight, but they
just want some quick cash by selling their body... (Who says only
gals are desperate?) But I dunno the situation in Singapore though.
The issue of homosexuality seems to be taboo here. If your female
classmate is a prostitute you may probably feel shocked. But if
your male classmate is a prostitute, you may feel more shocked and
disgusted! (unless you're gay lah...
)
