I met one gal a few years back on a free sex-dating site and we exchanged emails, then went on messenger, chatted on the phone a few times, then arranged to meet. I went to her house and within half a minute, she flopped her boobs out and we were off! Hardly internet dating (kinda missed out the dating part!), but it was great fun 
We met for sex a few more times, then it faded out and I haven't seen her for about 5 years. She was a bit of a moose, but had all the right bits and pieces - what more can a guy ask for? 
I'm very wary of dating sites where you have to pay to view/send messages, even during the "trial" period. I joined one this evening and have been bombarded by messages/winks. Being a bit of an ugly fuck myself, I hardly think they are genuine! So they won't be getting any money from me.
So guess who has a date with his own right-hand this evening then? Wish me luck, we may not get on!
