To me a well written profile with a detailed and carfully worded information doesnt mean you're fussy. It means you're taking the time and effort to let others know not to waste their own time and effort.
The choices you make when meeting anyone are always going to be based on your preferences. The moral code you chose to live by is a part of this.
The term 'swinging' covers a big area and means different things to different people - it's not just a bowl full of car keys at a party! Joining a swinging site doesn't necessarily mean you'll shag anyone and everyone, you're not expected to abandon your moral code before you join and you're not obliged to meet anyone.
