If you've ever been to the beach and went inside water, somebody with chlamydia may have urinated near you, and here you have it (most cases - no symptoms).
HIV - have you ever been to hospital? Are you sure all needles were sterile?
Gonorrhea? Did you kiss you girlfriend?
I think, the only way to end all this is to head to Bedok reservoir, the favorite place of many Singaporeans.
