@Colohotcouple - When we first started, the thought of what "could" happen was already adding spice to our relationship. This was before we even met anyone at all. It sounds like that's where you guys are.
When we finally got to meet people and found couples we clicked with, the "could happen" thing became more real and talking about it when we played was even hottter. Our first party was a Meet & Greet only, but we were still nervous as hell.
That first party did a few things. It showed us that most swingers don't look or act any different than anyone else. Regular norml people actually do this. While this may seem obvious, it was kind of a revelation back then. It also gave a chance to talk to others and learn from them and get to feel more comfortable in and about the lifestyle.
I'm not sure any amount of online time would have gotten us there. The Mrs is more of an in person social type, other than maybe Facebook. By talking about this a lot both together and with other swingers, we eventually got there. Once we did, it was like the flood gates opened, but it was very much just a trickle for what seemed like the longest time. Had we relied on online interaction only, it would have likely been a VERY long time to get where we are now.
