Is it safe to travel to certain countries as a gay person?

I recently had a discussion with somebody about wether or not it is safe to travel to certain countries as a gay person. I'm gay, and I don't have tinder or grindr or anything. I'm in a relationship, but only my friends can see my relationship status on fb. Yet, this person claims that it would be very dangerous for me to travel to countries like Egypt, Turkey, India or maybe even places like Poland or China. He suggested that especially in Egypt and Turkey authorities are actively searching for gay tourists to harm or lock up. So, is there any truth in any of this? I'd love to hear about it from you guys.
