So really to me the problem is that men, on average, struggle with expressing their emotions more. Asking those men to form healthy, loving relationships with other men is then a challenge. Not impossible, but certainly more difficult.
To me, Grindr is a symptom not the cause. If you are taught from a young age that men don't cry, toughen up and be a man etc, then sex is reduced to the physical act. Add in some emotional truama, which is again very common in the gay community, and the problem is exacerbated. Of course Grindr doesn't help and makes it all worse, but really they're just making money off the damage which is already done.
