Never knew that! I've never cut them off.

You didn't know that, Steragram because it's not true. The small flowers do not need to be removed, and will not discourage the larger ones, both are usually present most of the time. Give it a few days, the larger ones will arrive bramhallbill.

Lol Bamboo! I feel better now...

Are the small ones male or female or is that a fib too?

The double flowers on tuberous begonias are male, the single ones female. The only purpose to nipping off the females is so they don't set seed, but they generally don't set seed in the UK anyway.

ah ha ta
