Cypriphobia is a fear of sex workers or prostitutes and of contracting sexually transmitted infections or diseases.
The origins of the term are unclear. While it is obvious that phobia is simply the Greek word for fear, there are a couple of theories about the prefix. Some say it comes from the Greek word for the goddess of love, Venus. The Greeks called Venus Cypris because she was allegedly born on the island of Cyprus. Others believe it is simply a combination of the Greek words cypri, the word for an immoral or promiscuous woman.
Cypriphobia is sometimes called cypridophobia, cyprinophobia, and cyprianophobia.
