What's your budget?
You can get a (covered) BJ from a Hooker you can pick up down Ilford lane for £20 quid - it'll be 5 minutes and pretty unsatisfying and not worth it.
But if you're in a dire financial mess, have a Wank and save your money, or if you have a GF/Wife just work it out with her instead - as seriously, the cheap Hookers round there and everywhere are on the whole a waste of time, space and money and effort.
