Look, if you can read this, you need to know:
Your boobs are fine.
They're not too big. They're not too small. They're not too lopsided.
As a cis het man, I can only speak for my side, but I'm pretty sure my lesbian friends would agree, "I never met a titty I didn't like."
It's your mind, your smile, your courage, your eyes, your hope. Everything else is just gravy.
