Happy Birthday. Your thirteenth is important. Maybe your first really public day. Your thirteenth is the chance for people to recognize that important things are happening to you.
Things have been happening to you for the past half year. You have seven hairs in your left armpit now. Twelve in your right. Hard dangerous spirals of brittle black hair. Crunchy, animal hair. There are now more hard curled hairs around your privates than you can count without losing track. Other things. Your voice is rich and scratchy and moves between octaves without any warning. Your face has begun to get shiny when you don’t wash it. And two weeks of a deep and frightening ache this past spring have left you with something dropped down from inside: your sack is now full and vulnerable, a commodity to be protected. Hefted and strapped in tight supporters that stripe your buttocks red. You have grown into a new fragility.
And dreams. For months there have been dreams like nothing before: moist and busy and distant, full of yielding curves, frantic pistons, warmth and a great falling; and you have awakened through fluttering lids to a rush and a gush and a toe-curling scalp-snapping jolt of feeling from an inside deeper than you knew you had, spasms of a deep sweet hurt, the streetlights through your window blinds cracking into sharp stars against the black bedroom ceiling, and on you a dense white jam that lisps between legs, trickles and sticks, cools on you, hardens and clears until there is nothing but gnarled knots of pale solid animal hair in the morning shower, and in the wet tangle a clean sweet smell you can’t believe comes from anything you made inside you.
