Erotic massage in Delhi is a very weird mix of awkward and sexy. I’m not going to lie; it leans more towards the awkward. Most erotic massage parlours in Delhi are not very good at either the massage part or the implied sex part.
There are a few decent Indian salons like Amrita Spa (https://www.amritaspa.in/) at A-87, First Floor Basant Kaur Marg, Malviya Nagar, or Masti Indian Russian Spa (http://www.mastiindianrussianspa.in/) at A-165, Road No - 4, Street No. 7, near IGI airport. Try looking for the ones owned by Asians. They know what they’re doing and they are rather upfront about everything.
