I am new to this but need advice

If a snake breeds with another and lays a clutch of eggs does it have to breed again to produce another viable clutch, or is there some kind of sperm retention

...

Some years ago I had a corn snake that mated once & had viable eggs for 5 years total... So to answer your question, you never really know what will happen-
it's a wait & see, fingers-crossed (depending on what you're hoping for). And some snakes are just so compelled to reproduce they do so by parthenogenesis.

You may be able to locate a breeder/ reptile group local to you that may be able to help you out. You could maybe check facebook for reptile groups in your area (though not sure, never used facebook), could maybe make some connections with someone at your local reptile shop if there's a decent one around you. Not sure if that will be accessible to you, just trying to throw out some ideas.
