It can be a big decision to start online dating. I know many people who have luck with it.
Like real life, it offers good and bad options. Online dating is a way to meet people you would never come across in your daily life.
If you did come across them, you would probably walk by them on the street or stand behind them in line at the grocery store and never speak. The most mainstream and popular dating site is Match. Millions of single men have posted themselves, hoping to meet you.
There are so many people on the site that it can take weeks to wade through all of them when you first sign up. I live in a major city and within five miles of my apartment, there are approximately single men in my age range. You can get a feel for the site without making a monetary commitment.
