From guys perspective at my age I would be completely lost if I was single and starting to date. I have not dated for about 19 yrs now and I would most likely be a mess. Dating again for me is what wakes me up at night in a cold sweat.
Almost all of the longterm successful relationships I know just happened and neither party was actively looking. That is how I met my wife, I gave up in frustration and stopped looking. That allowed me to relax, re-focus and "see" life without hormone glasses on. Then it just happened.
If I was in the singles scene again the only hope I would have is to just to stay engaged in life but always keeping my eyes open. Men in my age group, just like women, have been through some bad "gunk" in life and have no idea how to impress anyone on a date. The more we would try the more we would screw it up. We have all experienced performance reviews before and it's really hard to get a pasing mark on every item on the list. There is always one or two criterias that get the "needs improvement" notation.
