The Gigolos 2006 one on netflix

Sacha is an aging, well-established London ‘male escort’ with a select clientèle of weekly socialite ladies, such as baroness James, who expect an impeccable service he can only provide thanks to his in-living ‘orderly’, handsome ‘clever Trevor’, who moonlights as nude arts class model. Ben is a rising novice, who seeks their coaching. When Sasha makes a bad fall, Trevor must cover during his recovery, but jealous Sasha is far from grateful.
