My favorite person-to-person LPSG "encounter" happened in 2005 or so. Looong before webcams and smartphones, Chat (AIM) or telephone was about it for long distance communication. I had gotten to know a couple of the women here (yes, actual women were quite common on LPSG!).
One evening one of them wanted to hear me get myself hard, stroking and then cumming via audio chat. We setup a time, made the connection and she asked me to describe my hardening cock and talked dirty to me while I quickly got very hard. She wanted to know how it felt in my hands and the pleasure I was feeling. When I inevitably got to the point of orgasm, she went quiet as she wanted me to express myself fully!
I also became online friends with some nice people from here that were also members of a few other websites/forums for adults (now defunct) where there was a much more even male/female ratio of members. There were at least two women there that wanted to meet up bt the closest was over 1000 miles away. I did have an open invitation to let them know if I traveled to their area but that never happened.
