For myself, I finally reconciled with having a small penis around the age of 30yo (i'm now 55yo) Before then, it was an absolute millstone around my neck. It obviously prevented me from having many sexual experiences all my friends were having, but it just added to my overall lack of joy, in life and in myself. I was angry, frustrated, lonely, very jealous, embarrassed, anxious and nervous around women, and basically just became more and more withdrawn and more and more submissive. By 30yo, I was just done with my wife constantly cheating, never fucking me, lying etc. and from that, Googling cheating wives, finally found out what a cuckold was... and more importantly that most had small penises. From that very day, I finally belonged, i'd found my tribe and I realised I had been dealt buckets of lemons and started to start making lemonade.
I couldn't imagine my life in the last 25 years without having and loving my small penis. It may never had a lot of pussy in its life, but its a gift that keeps on giving... it has brought me a lot of joy in those 25 years and still does to this day
