Newby

Hi all. New to this and just joined the site so u I hope I dont sound silly asking this.
Im a single guy but find it a turn on watching people I have tried some digging spots I heard about but not a lot of action or luck there really.
I was wondering if swinging is only really open for couples or if singles can join in aswell and are accepted by couples.
I am open also if there are any females out there single and looking to join this I am more than happy to go along with them aswell.
Hopefully that covers all my initial questions and doesnt sound too sill apologies if it does x
