Guess you'll be getting DMs from GOT regs seeing if you'll go for a beer and ex chat...
There's a difference between discussing sex and sexual issues and bragging. Witless, boorish bragging. I know a few who fall into the latter. Including one lad who started boasting about his exploits whilst waiting for a funeral service to commence.
I`ve got a mate just like this too, yet the write ups he gets from his ex`s afterwards are less than flattering.
He`s like a fifty something version of Jay from the Inbetweeners.
It`s really quite sad and boring.
