It looks like you gave me a tough one. Okay, here’s what I think. There’s a lot of good stuff in here. I instantly could tell it must have been a lot of fun to write. There are some powerful lines here but what I think is it needs to be compressed. Strip it down a little, focus more on core and revolve around it. If you were going to leave it basically as is then some periods would help in some places to handle the shifts.
First Stanza:

after 20 years I can still taste my nuts as (delete “as”)
i sat on the bench, praying (maybe say “sitting on..”
to the Virgin Mother to (maybe even delete “to” here)
help me not to peak at their blue panties. (I’m not sure who they are so maybe use “her blue panties” instead)


Second Stanza
I still hear my screams in Olangapo’s whorehouses (I don’t understand the reference to “Olangapo’s” and since it’s called “whorehouses” it leads me to believe perhaps it’s a franchise or something)
from nightmares of their smudged waxen lips (I don’t like “waxen lips”)
fresh from their boyfriend’s cocks beneath (I like how this sounds it seems to not flow with the previous lines)
back seat high school letter jackets (like it)
admitting in 5th period lunch how their fathers
cried to stupor begging (confusing)
tenderness while their mothers drank to
oblivion beseeching death. (more confusing, I feel lost in what you’re trying to say)

3rd
I like the last line. I’d rework the rest of it

4th
I don’t get the 2nd and 3rd lines.
Like the 4th line
I’m later confused by what wasn’t confessed. I like it but I would like it to be clearer to help tie this piece together. I think the last 2 lines work well with that too.

I hope that helps.
