DONT!!! Don't be like some of these losers on gag, go out in the REAL WORLD and interact you know, face-to-face! Don't form habits of just living ur life virtually and rotting away. Too many low testosterone guys these days are like that.
I have never tried it before but my friend mentioned an app called fav talk which allows you to talk to people of similar interests and well you can alter the purpose accordingly so you could put in something like single, dating, blind date? It's important to make friend relationships first, if you ask me （＾_＾）
There's a great thing called social interaction. Just leave your house, and go meet new people. There's usually no age limits unless you're signing up for dangerous activities, for example. It's also a lot of fun. :P
