Swansea is a punting graveyard. I would highly recommend welsh brunette who is based porthcawl/Bridgend area but I gather she's now only seeing regulars?? Not sure what look you go for but I would highly recommend welsh barbie. I think she's got a new profile but for the life of me I can't think what it is. As the name suggests however - she is very much the barbie - hair extensions, false boobs etc. great girl though and very friendly too.
I'd seriously avoid streetwalkers though just not worth the risk
