If I have forgotten locking my door and I do not have a memory of it. Is it natural to say ""I forgot locking my door."?
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
I forgot to mail the letter. (I didn't mail the letter.)
I forgot mailing the letter. (I mailed the letter)
This is the same if you substitute "didn't remember" for "forgot"
