Which version of the word "dry" is suitable to question about the next step of instructions

Question

Which one of these sentence is correct?

1) What do we need to do after we have dry our body?

2) What do we need to do after we have dried our body?

Answer 1

As @Weather Vane said in the comments:

✔️Yes: What do we need to do after we have dried our body?

You could also say:

✔️Yes: What do we need to do after we have dried our bodies?

.. if you actually mean there are multiple people.

In conversational English, you can say:

✔️Yes: What do we need to do after we have dried off?

The phrase “dried off” ^{((Definition))} implies your body.

Or you can use the present tense

And finally, if you mean in a more general sense, for example, if this is a repeating situation, you can use the present tense.

(Notice the word “have” goes away (disappears).)

✔️Yes: What do we need to do after we dry our body?

✔️Yes: What do we need to do after we dry our bodies?

✔️Yes: What do we need to do after we dry off?
