Quote:The past decade has witnessed the growth of niche dating websites - from Amish to Zombie enthusiasts - but a particularly burgeoning sector has been the proliferation of STI dating websites.

Now there are so many, there are Top 10 lists.

Many have taglines such as "Stay positive! Find Love, Support and Happiness" or "Plenty of Positive Fish". Some sites, such as H-YPE or H-Date, are aimed specifically at people with the most common types of incurable STIs, such as herpes and HPV, which causes genital warts.

"If you have just been told you have herpes or HPV and you feel like your life is over, well, we are here to prove to you that it's not. In fact, it's a whole new start," it says on H-YPE.
