Trust me that many fine romantic things can happen after the age of 23, man or woman. I did not even have dates until I was about 30 years old. So don’t worry about your age now. I do worry about my age which I will not tell.
BTW, it is a number’s game, but the numbers can be daunting so be open to any way of increasing the numbers of potential partners — online, through friends, work. Things come to you when and where you’re not looking for them, but that includes places you’ve looked before. Here’s an example: I met a lady on match.com and matched her with a friend and they are dating. The only advice that really works is to not obsess over any specific advice.
