Yes. Met my DP on POF of all places. He messaged me first and I wasn't keen on initial glance as he had only one photo on his profile and he is dark blond with blue eyes, whereas my 'type' that makes me go weak at the knees is black hair brown eyes. 
But his opening message was really warm and genuine and so I ventured into a reply.
After two weeks of messaging, swapping more profile pics and finding out we had a so much in common, plus mutual friends and the exact same sense of humour, we decided to meet.
He's a chef and baked me chocolate brownies for out first meeting. He was a lot keener on me than him and I found it sweet, but a little overwhelming too, but I went with it. We went to a huge crazy golf course and then my local, where we stayed until a lock-in and I drunkenly snogged him. I regretted it instantly as I didn't think I fancied him. But we got on so well, I was open to seeing more of him.
Second date he cooked a beautiful dinner for me, third date we went out for a meal and he bought me flowers. I still didn't "fancy" him, I thought he was good looking, funny and kind, but there was no spark. A month later we had the test of a seaside break and after three months together it was Christmas and he came over (we both aren't huge fans of big family Christmases) and had a lovely day together, with a meal we both cooked. He stayed for two weeks, we had a relaxing time, no work to go to, lots of laughs and that was when I started to unexpectedly fall in love with him.
We have never argued in the five years we've been together, he moved in three years ago and we laugh until we ache every day and he was my absolute rock when I lost my mum a few weeks ago.
I'm so glad I pushed away my doubts. It was a slow burn for me with him and it seems to be working. I count myself lucky every day for having such an amazing man, I love him so very much.
So, yes. What have you got to lose? Go for it!
