My experience has been similar to what has been experienced by many on online dating. One thing it can do is help others who or shy or introverted to take a chance and work on your communication or have to the nerve to start a conversation. It think that the marketing of these sites doesn't help as does ones expectations. I have only met a few women online and while it haven't had any success yet, I wouldn't have met them otherwise. From what I have observed is that people met their partner in all kinds of places like at a concert, a party, or other social settings. Sometimes people meet each other in volunteering or taking up courses. I have tried these ways as well, and while I haven't been successful, I have had a lot of fun. Whatever I do here has to at least be enjoyable and fun, because if it isn't, then why bother.
On any given dating site, the sex ratio is commonly unbalanced. A website may have two women for every man, but they may be in the 35+ range, while the men are generally under 35. Little is known about the sex ratio controlled for age. eHarmony's membership is about 57% female and 43% male, whereas the ratio at Match.com is about the reverse of that. When one gets into the specialty niche websites where the primary demographic is male, one typically gets a very unbalanced ratio of male to female or female to male. As of June 2015, 62% of Tinder users were male and 38% were female.
