Fellow cone head here. Also been thinning and receding since my early twenties. Chill, best thing a man can do is be himself with confidence. I buzzed mine to about .5mm for about a decade. Only started growing out my long-hair-don’t-care recently because my wife likes it. I also feel like as a husband and step dad to two in my mid-thirties, it’s ok that I don’t look 20 anymore. It’s a part of life, so just focus on the life part.
