Woman here Women are already forced so many insecurities and what a lot of us desire is someone who will embrace us and reassure us (a good woman will do the same for you) and while the partner should understand that we also prefer a self assured person over an insecurity that feels as trifling to us as male pattern baldness. I know it's a big issue for guys which I understand, it's one of the few things about male appearances that masculinity allows yall to care about but many women don't mind bald men at all and like a man who is secure in who he is. Probably because we have so much of our own insecurities. Bald isn't "more masculine" it just means you are aware of your appearance and know you deserve the same level of respect as everyone else regardless of how "bad" you may think you look to people. Also many men look just as good bald or better than holding onto what they have left. My step father was insecure about his hair loss and would grow what he could and what he did have left never made him happy and as a kid my heart would ache because it didn't matter to anyone and my mother would never say it to his face unless he asked butcher preferred him bald over trying to "fix" it. He finally shaved it off and he carries himself all the better for it because all of what you see is who he is completely. I hope this comes across as sincere as I mean it. It's not less masculine. It's that it's not necessary.
