As is the case with most services these days, there are a growing number of niche dating websites to be found in the far-flung corners of the internet, but what you may not realise is just how niche some of them actually are. Below are 5 of the most 'interesting' examples of dating websites which statistics indicate you will probably never have the urge to join.

1. DiaperMates

DiaperMates is the internet's premiere destination for all those interested in meeting people who enjoy wearing diapers and/or looking at other adults who wear them. After you've re-read that sentence, consider the fact that (according to their homepage) they currently have over 11'000 members and you'll begin to realise that there's a market for even the most unassuming fetishes.

2. The Ashley Madison Agency

'Life Is Short. Have An Affair'. With a 'trademarked' greeting like that on the homepage, you can't say the Ashley Madison Agency are shy when it comes the fact that their dating website caters specifically to married people with a roving eye. There's even the option to quickly visit a fake home renovation website at any moment by pressing a panic button. So romantic.

3. VeggieLove.com

No doubt the picture above has already given you the wrong idea about VeggieLove.com. It is in fact a dating website devoted to hardcore meatists; vegetarians wishing to find love with other people who choose the sausage-free way of life. Membership numbers are unknown.

4. Women Behind Bars

Unfortunately, Women Behind Bars isn't a site dedicated to pointing you in the direction of attractive ladies with a flair for cocktail making, however if you're looking to start a relationship with an incarcerated female, this place could be just the ticket. Just realise that it could take a few years until your first date, and that's assuming she behaves.

5. Trek Passions

Trek Passions is basically a dating website dedicated to geeks and nerds, more specifically those people who live for Star Trek and couldn't imagine entering into a relationship with someone who couldn't recite the Wrath of Khan script. Please Note: The picture above in no way relates to the females who use the aforementioned website.

Obviously, if you're looking for a normal dating website full of regular people, and one which is 100% free, go no further. Well, just a little bit further by by visiting the Free Dating Homepage.
