Yes, I have a holiday home in Goa, and have travelled around extensively.
There is lots of sex on offer, most for free, as young Indians have a thing for white skin, and having sex with a "European ".
Grindr is very active. In the big cities the first 50 will be within around 500metres.
Do ensure you use protection, as disease is on the increase in India.
Several of the big cities including Delhi, Mumbai, Bangalore, Kolkata and Hyderabad have weekly gay events/clubbing which you will find advertised on Grindr or just ask.
Most guys are pretty polite and discreet however, so do bear that in mind.
Lots of offers for massage 💆♂️ on the apps too.
