My experience with online dating sites is very limited, but was not pleasant. One of my friends talked me into signing up for Match dot com a year or so ago since he met his sweetie on there, and because I haven't met any people (men or women) to pal around with since moving back home after living out of state for 30+ years. I still have casual acquaintances and old H.S. mates, but most of them are married and pretty much have all of the friends they are interested in having at this point.
Who knew it would be so difficult to meet people once you are retired??? Anyway, after much nagging from my friend, I signed up. What a disaster/joke/unpleasant experience it was for the whole month I stayed active. I was contacted quite a few times - by guys half my age wanting to "experience a good looking cougar" (sorry, fellas, I raised my boys and don't want that job again); by guys who lived across country who thought if I really loved them, I'd move to where they are (love them? I didn't even know them and, besides, I made it clear in my profile I was not looking for marriage or cohabitation). Some guys made crude and rude ****** comments. Others wanted personal information I'm not willing to share (finances, etc.). A few were actually very nice guys but with whom I had not one thing in common. I actually went out with one guy one time. He was perfectly nice but he still had children at home (if I want to hang out with children, it will be my own and my grandkids), a long story about a wife who had committed suicide (TMI), and oh. . .we had nothing in common. After that experience, I signed off.
