I don't know how old you are but I went through the same fase. I'd say late 20's early 30's. I'm now 37 and don't even think about it anymore.
Thing is, as you get older you stop caring about it, I even bought a 3 bedroom house planning for a family in the future, but for a few years I've just lived my life as it is, I started running and swimming 7 years ago, I also started playing the guitar and saxophone, and with a full time job and taking care of my home and garden I just don't even have time to have a girlfriend much less kids.
Just enjoy life, there's a lot to get excited about. Women and kids are way more work and trouble than they are worth. With the money you save on that, enjoy yourself.
