There are plenty of disabled people still getting it without paying a cent. Sweaty... speak for yourself.
Conversely though there are others for whom dating sites are not effective.
But you can't say... oh X person is missing a leg so they can't get a date... do you know how many of the population of Earth is missing a leg? they could all hook up together and join in activities together like the 2 legged race!
Unless you think that people who have those disabilities also do not want to date other people who are in the same field as them.... conversely there are people out there who both don't give a rats ass what someone else looks like on the outside but instead loves them for the person they are, so wouldn't matter if they were hawkingesque in looks but a great personality. Just think.... no matter how bad you are at dating / confidence... there are a couple of million girls out there who are less confident than you and feel the exact same way.
Just gonna put it out there, any of the people who chat to each other on here, if you can do it without coming off like a complete bellend you can take those conversation skills and try your hand at applying them to something like a WoW RP server where you can anon chat to people with a shield up to hide your identity, scoring a few times in goldshire inn could do your confidence the world of good.
