Seed vendors are re-sellers. They don't have any boys around the shop.

Pollen doesn't ship well, at all.

Grab a cutting, root it up, and abuse the photocycle. It'll herm for ya, and you'll get some pollen.

If you're outside, you'll prob get some pollen naturally- couple seeds, anyway.

If you let the plant flower forever( several weeks past ripe), most varieties will drop a few bannanas, as insurance.
