I can only recommend an erotic massage place near 10th arr, it is Ko Samui Thai Massage at 17 Rue Lucien Sampaix. I went there last March. I paid 120 euros for an hour all in. It is pretty full on, the masseuse did a full on sexy stare throughout, we started with a sexy mutual shower washing each other, then sexy massage. I opted to finish with a 69 but FS may have been available I dont know. It is almost tempting me back to Paris just for this.
