There are some really good erotic massage studios in Lisbon including a few which seem to be a front for brothels. Jardim do Edén (http://www.jardim-do-eden.com/pt/) at Ave Joao XXI 43 is widely known as one of those spots. Some salons disclose their physical address in Lisboa only via WhatsApp, and they’re usually up for both incall and outcall massage services.
Massagens em Lisboa (https://www.massagemlisboa.com/) at Av. Fontes Pereira de Melo 31 is a genuine tantric massage parlour. They might tend to be a bit on the higher-end side of the market but a hand job finish is definitely on the menu. An hour massagem sensual or massagem erótica will cost you around €100 in most salons in Lisbon. You could also give it a shot with independent masseuses (massagistas) in Lisbon, who will advertise usually on local classifieds sites and escort directories.
