These sites never worked for me. I tried and it was such a stress and also a complete waste of time.
I had many romantic relationships and met all those men in real life, not on the internet.
What about speed dating? Have you ever tried it. I have not, but it sounds like it is not a bad idea and definitely more promising. 5 minutes of a live conversation will tell much more than 20 pictures and several messages. If I were single, I would give it try it.
