BUSINESS INSIDER - Mar 28 - STD-positive dating sites such as H-YPE.com, PositivesDating.com, STDmatch.net, and PositiveSingles.com seek to match singles who have the same STDs. When signing up, people are asked to pick their STD from a drop-down menu. But there are ~100 different types of HPV out there. Even if both users have the same STD, they could still swap strains. Plus, if they have one STD, the chances that they have more than one are pretty high. These sites let users select only one.
