Which app/site did you use? I've used two and I quit the first one (POF) within a week, the second one (OKC) was better suited for me.

I had my OKC profile on then off then on and off several times before I even met a guy I mildly liked, mostly because I just it disgusted with it all. I got messages from guys I didn't like, but that's life. I also found that if I messaged a guy (even if we matched) I'd NEVER get a reply back, but if I just liked him or matched with him and waited, I'd get a message...which was odd, but I went with it. I eventually figured out how to only bother looking at the guys who liked me vs everyone, as they're most likely checking their profiles.

After about...three solid months of online bullshit ( oh god and terrible dates) I swiped a guy and he was perfect for me. He had only been on the site for a week and I was his first match.

It takes time. Keep at it. Also, I highly suggest before you go out, FaceTime or Skype them to see if you have any chemistry..it really saves time.
