What do you mean by discrete? Just check Adultwork like the rest of us and search 'massage'. Most incall places are discrete....
All massages are
discrete as each one is performed separately from all others.
If he's worried about discretion though, some dodgy massage parlours in London are more
discreet than others - i.e those which are located on a side-street where other people are less likely to see you going in/out as opposed to the ones on Shaftesbury Avenue for example.
