I was nervous the very first time (at a brothel in my case), but once you do it, it becomes so much easier after that.
Perhaps go to a recommended brothel/parlour or whatever you want to call it, in your area, better yet go to a recommended WG in said establishment that charges a reasonable amount
Just try not to over think it; it just makes the apprehensiveness worst
Just pluck up the courage and walk in, remember they have seen it all before including punters far more nervous than you
If it’s unfortunately is a bad punt post a review on here & then look for better punt, as there are some excellent WG’s out there that will give you a fantastic time
So go and pop your punting cherry and become a member of the punting club
