I was struggling with this sentence from Yoshimoto Banana story called ミイラ

> ...それは普通のセックス **で** 普通に気持ちいいというものではなくて、何か歪んだ喜びだった。

My translation: it was kind of perverted pleasure, (何か歪んだ喜びだった) it was
ordinary sex (それは普通のセックスで) (but) it wasn’t ordinarily pleasant
(普通に気持ちいいというものではなくて)

How can I tell if というものではなくて negates only 普通に気持ちいい or if it also negates
それは普通のセックスで? (so the translation would be "it wasn’t ordinary sex) Would there
be a comma? Or am I getting this completely wrong?

I know this is kind of confused! Thank you so much for any help!

question
sentence
Is で marking end of the sentence in this case?
You have parsed it wrong. That で in bold is not a copula (だ) but a simple case
particle that marks a means/method/reason. 普通のセックスで here means "by/from
(having) a normal sex".

> それは［｛普通のセックス **で** 普通に気持ちいい｝というもの］ではなくて、…
>
> (Very literally: It was not an I-am-ordinarily-pleasant- **by** -having-an-
> ordinary-sex thing, but ...)
>
> → It was not an ordinary pleasure of an ordinary sex, but ...
