Peter, have you looked at Craig's List UK? You might be able to find a good therapist there under the therapuetic section. Do be careful, some hookers cross over with promises of massage like a genuine therpist would, but are really after the trick.
I just made a post in the other massage thread as to how to deal with erections, should they happen during a massage. Give it a glance.
Out for life, liberty, and the pursuit of cuntishness!
