Obviously it should be mentioned before things get physical, but where is the line?
We already have dating websites that cater to every subset of the population from the Amish and adults who wear diapers to Ayn Rand lovers.
And the potential dating pool for singles with STDs is a lot bigger.
Statistics show as many as one in four women - and almost one in five men - has herpes.
Yet there is still shame attached to being diagnosed with a sexually transmitted disease.
But these dating sites help challenge the stigma by bringing the information out into the open.
They allow users to filter by gender, age, and location; but they also have an extra menu where users can specify if they are living with herpes, HIV, HPV, hepatitis B, HIV, AIDS, syphilis and even thrush.
Some critics claim that the sites could further ostracize people living with an illness.
But after browsing the sites, it's clear that they provide more than love matches - they also offer a supportive environment and a safe place to ask questions and become educated.
Plentyoffish dating forums are a place to meet singles and get dating advice or share dating experiences etc.
