But I need more advice and tips to impress him

He has not mentioned me using a strap on yet but should i assume he will want that? I have a little experience with strap ons but not much
He says he wants me to punish him if he does something the wrong way etc...
I have done a few BDSM sessions as a provider but I am definitely amatuer and need help/advice!
He calls it femme-dom not bdsm.. are these different??
