Barber shops where there is a girl or girls milling around. Go in for whatever it is you're looking for, haircut, Indian head massage, shave.
If there is a girl in the place, you'll soon be asked if you would like a body massage with a girl by one of the guys working in the shop.
I accepted twice and was led into a back room, somewhat cramped and noisy where I had a body massage, mutual touching and kissing. Trying to remember what I paid but I can't, although I know it was cheap, very cheap!!
This was in and around Delhi, whether it's the same nationwide I can't say, but I don't see why it wouldn't be any different.
