Cheers for all of the replies and PM's folks! I've pretty much made up my mind now, so now all I need to do is calm my nerves and make the booking :P
To be very honest, after living my whole life in Ireland, I'm not a massive fan of Irish women at all and have always gravitated towards foreign women (lots of different nationalities too!). That's just me though, of course I'm sure that there are great Irish escorts but they aren't for me, I think it might be something about a foreign accent that grabs my attention & turns me on.
