I think, as in all walks of life, referrals of this nature are a good thing. After all, what can be more reliable than a recommendation gained from personal experience.
A gay friend I often chat to in the gym sauna once referred me to a male masseur who he said would never fail to disappoint. That was last summer and now whenever I need a great, full body massage with all the extras, I know he's just one WhatsApp away. I would happily refer him if asked.
