I don't know if it's just me getting old...but i do wonder how swinging at a young age will affect the future of some people. I think that as we get used to certain activities we need more stimulation to get the same effect. The first time u see porn for instance its amazing, then it gets boring.
So if you start to swing at the age of 20, and have seen and done every kind of play by 30..where do u go from there?
