I'm a single fella completely new to the swinging scene (having not been able to talk previous partners around, plus not really being sure myself I could see it through), but I think it would increase my general confidence.
If I'm very lucky I'll be getting my first swinging experience this weekend (in the process of arranging), so I might have a better idea come Monday! (here's hoping we get on well)
I'd never even got as far as talking to people on the phone to arrange a get together before.
Maybe it's just increasing age decreasing my inhibitions, making me more open minded and adventurous.
