Normally I wouldn't talk about a dating site, but this one has a very unique concept. Prescription4Love.com is an online dating service specializing in people that have unique characteristics such as Cancer, Diabetes, IBS and IBD, Obesity, Deafness, Allergies, Hepatitis, Infertility/Impotence, HIV, Herpes and Recovering Alcoholics. Imagine that, eh? Even if it isn't something you would pursue on the romantic side you can find people that have similar issues and form a bond with them this way.
The site itself is completely self-explanatory. You can do a quick search, search more in depth by issue, and find someone right away and get started. This is a site that allows you, no it actually forces you to be honest, but they make it easy to do so. This is a place not to be judged on what you have, but who you are.
