This is the first time I have ever been bungee jumping.

4. This is the first time I ever bungee jumped.

   Are the above sentences grammatically correct (minor differences in meaning aside)? Which one sounds the most natural? Could the "been bungee jumping" of the sentence #1 be construed as a variant of "go fishing" (where "go" is replaced by "been")?

You can use (1) (2) or (3), but (4) (5) and (6) are all wrong.

Yes, in (1) "bungee jumping" is the equivalent grammatically of "fishing".

Thanks. so it's not present perfect progressive (like "I have been studying English.")?
