I empathize with this situation because it is something I had struggled with for years. There is no right answer, but I will say that free dating apps and sites are a hotbed for guys using it for sex. That's just my personal experience talking.

If you're serious and you want to try it out, I used Eharmony to find my guy. I know its not a popular opinion to spend money on a dating site, but if you want quality, sometimes you have to pay for it. It worked for me and it might work for you.
