I know about the anti-LGBT+ policies and laws in Russia... so the simple fact that someone raised in that environment is open enough to give a furry VN with gay characters a chance, even if he considers himself heterosexual, is already a very good thing and deserves my support. Also, as I wrote to him, it could be that perhaps he was conflicted between what he really liked and the fear/pressure of his environment.
About 10 years ago I met a 16-year-old boy from Spain who was curious about these things, and at first I got along very well with him but suddenly he became unfriendly, almost homophobic, I think his conservative religious parents discovered something and brainwashed him.
I also had other friend, a 13-year-old girl, on a text roleplaying forum, from Ecuador, who wrote better erotic stories than I at 22... but one day her parents found out about this and forbade her from using the computer, she managed to write me a farewell before.
I had a gay male friend from Mexico for a few years and I saw that he had some awkward moments with his truck driver father when he came out as gay, his parents are divorced and he ended up moving in with his mother, he is quite happy now and have a lot of fun at night, a bit too much for my taste but, oh well, hahaha.
And I have a Polish-Russian friend, a fan of MLP FiM, so I know there are nice Russians out there.
So I know that, in some places more than others, it can still be hard to be true to yourself and what you like. Even in fairly modern/progressive Western countries where gay couples can legally marry and adopt children, there is still usually some internal struggle because there is always the idea of what is "most normal" and the ideal of a typical family, and if you are one of those who feel that you were "born in the body of the gender with which you do not identify", it is even more complicated because there is also a lot of controversy about it due to whether it is okay to "transition as young as possible" since a true gender change that does not involve lifelong hormonal treatments and negative health effects is not yet possible.
