Mating question

[Stoney Meadow Maple]

So our drake seems to have figured out what to do with the ladies, he favors the Pekins, occasionally a Rouen, he’s left the runners largely alone. When he does the deed, it doesn’t look pleasant but he’s not tearing out feathers Or anything and the whole interchange lasts about 15, maybe 20 seconds.
Is this just a learning curve or is this the real deal? If so does that mean we have a fairly gentle drake? Is this because he has no competition and learned from no one but nature?
I hear about drowned ducks, feathers torn out, bleeding, and so far nothing like that is happening here.
Occasionally you will see 3 runners on top of each other, but as they are the same size and all hens I think they are confused but it seems harmless enough.

Thoughts?

mating season is over for the year, next spring he will most likely be more aggressive

If it’s that short he is not getting the job done. The drakes do seem to prefer the full figured ducks. Things should quiet down in a month or two then pick up near the end of winter.

He's your only drake and you have plenty of ducks for him; there is no need for him to be aggressive.
