Hmmm, it's an interesting one!
I met my first 'serious' boyfriend on the net, we went out for 4 years and in then end, we just wanted different things, he was a lot older than me and wanted to settle down and do the kids thing, I wanted to go out and get drunk and sleep around!
My next b/f after that was also from a net meeting, but it was through a forum, we were both on the governing body and at a conference, we got on rather well. However, after a couple of months of fun, it all went horribly wrong, but I blame that on the fact he was a fucked up son of a bitch!
My present master, I also met on the net (I'm seeing a patterm here!) and he is wonderful! We clicked almost immediately. I was into BDSM, he was into BDSM, and it wasn;t until our thrid, r/l date, that we found that one out, it truely was a match made in hevan!
I've met loads of people that I speak to on the net and enjoy it, I've had one or two vaugly dodgy meetings, but on the whole, they have been great fun!
However, I coudn;t envisage having an online relationship with anyone be it freindship or love, unless I had eventual plans to meet them. I had one friendship like that, but it didn;t last for very long, because we lived so far apart, it just wasn't going to happen. I did however, go to the states to meet some people from the forum that my fucked up ex boyfreind was on, that was great fun!
