Being pathetic, scaredy and undecisive loser is a crime to yourself and to your gender in general. I saw that you try very hard to push your own look about your MC being normal but "just different" from other men, but in reality he is just a horrible failure of a male and nothing else. Its just painful to watch his behavior and reactions. I'm not saying that I myself a representative of the ultimate alpha pack, just an average dude like a lot of others, but I lived life and have enough life experience to tell you that I wouldn't even shake hands with your MC IRL if I knew how much of a pushover beta stands in front of me.
MC's sister, on the other hand, is straightforward and decisive, knows what she wants, and acts on her desires, while MC, in comparison, is just literally empty space without any kind of backbone on his back. What will happen if shit hits the fan in this family? Your MC will definitely not be able to solve serious problems, protect family, or rebuild (metaphorically) anything, and just be sitting in the corner dying from hyperventilation
In reality he would never be able to make average girl's panties wet, only his own) That's why a lot of people mentioned your male character in a negative way.
Sure, you can continue to answer every negative message about your MC with your defenses and justifications of MC's every breath, but if the average man where I live would be like MC, then Russians would destroy my country as they claimed in the beggining - in a few days.
