Confundled, I had a few dates with a guy who had lost an arm. I couldn't care less about the missing arm, it was his "can do" attitude that made me like him so much, BUT his one problem was that he thought his missing arm meant more to me than it did, I stopped seeing him because I didn't want to spend all the time trying to convince him that I really didn't care about it, a shame really, he was great.
There will always be some idiots that care too much about disabilities (I have a disability myself), but it is important not to let a few idiots put you off of the dating game.
For those looking for positive stories of OD, I met my ex partner in POF, and as many others who I talked to back then in the same site, he was nice, polite, lovely and he never sent me anything offensive. At the end of the day the relationship only survived for three or four years but I have no complaints about him, my son still introduces him as his step "dad" and we still see him as part if the family even when the relationship ended years ago.
Apart of some weirdo with stalker capabilities, I have never had any problem with people in dating sites, but I act in there in the same way that I do in normal life, I treat people with respect and I am treated back in the same way. I ignored those that didn't deserve an answer.
I have met some interesting people, some writers, some artists, some very successful professionals, and even a BBC television presenter. It took me a while to find my current partner, who is also lovely, but I certainly had a great time meeting some of the others that were not exactly what either of us were looking for :)
So don't be put off because of the bad stories, if you are a little bit like me (a parent working in a female dominated environment, with not a big inclination for partying and nights out), you may find that the only realistic way to find a partner is to download him from internet
