I understand that "perfect participle" shouldn't be used with the present, should it?

I wanted to convey this meaning

The man, who told you the funny stories (yesterday), is my cousin.

Does it mean that perfect participle should only be used with the past?

With your new example, you need to use "who told you" as you have done. You do not need any commas in your sentence.

The man who told you the funny stories yesterday is my cousin.
