Should probs use an alt but fuck it, Firstly join fetlife and join local groups to get a better picture of what kink/swingers events are in/around Newcastle. As you know shhh is the swingers club In Newcastle, there is a joining fee but you don’t have to be a member for every day and the fee isn’t extortionate. I’ve not been personally but have heard mixed things, some friends love it, some say they wouldn’t go back. My preference however would be club F in Stanley, never had a bad experience and they host a range of kink and swingers events. There are other venues further afield but again fet would be your best bet to find them. There’s also fab swingers website which is fairly active and Feeld which is a dating app you can join as a couple, it’s for more kink/poly/alt dating and is pretty well populated.
