I know that Tinder is the most popular dating app and there should the most amount of girls, but I still have no matches. How can I change that?

Buy premium account. This should help

I don't think that wasting money on Tinder premium acccount will make any difference. The best solution for you would be trying other dating platforms. For example, you can check out these best sex apps. Read the reviews to learn more about them. I'm sure that you can easily find here something good. Make sure to check it out. Good luck with it, friend.
