Swinging in Northumberland

my partner and I are looking to introduce another to our bedroom  proberly another male but maybe a couple 

Any advice 

First bit of advice: if you're a couple, you're swinging as a couple, and you're advertising on here as a couple, you might want to change your account from "single male".  Put a bit of detail on your profile describing who you are and what you're looking for (and not looking for).

After that, post an ad, post in here, get yourselves known in the chat rooms, go to socials.  When you find someone you like the look of, spend some non-swinging social time with them in a public place.  If you're all still interested after getting to know each other a bit (and your "nutter/creep/dangerous weirdo" alarms haven't gone off), I'm sure you won't need any help with the rest :-)
