I think we need to differentiate between escorts who have bareback videos but don't offer bareback, even secretly, to punters and escorts who have a sex life outside of work with partners or work in the porn industry.
Pretty much every escort that has a partner, casual or more serious, has bareback and escorts that work in porn regularly have bareback with male porn performers, that doesn't mean they offer secret bareback bookings to clients who are just clients.
If punters are worried about escorts who offer any kind of bareback to anyone then they should probably quit punting or start a new thread about any escort who openly has a partner or does porn.
