Use second conditional

[Phoo]

"Yeah, well I went to boarding school with four hundred boys. Any sex I had would've involved a major lifestyle choice."

Did he actually have a sex with a man or just subjunctive past?

So confusing!!

[Diverhank]

No.

[Phoo]

Oh, good then.

He said he didn't have sex otherwise he would have been a homosexual.

"Any sex I had would've involved a major lifestyle choice"

I think Past Perfect Subjunctive Any sex I had had should have been used here but it is clear that the Perfect conjugation with would've involved, indicates that the condition expressed in the clause "Any sex I had" is false.

I thought so too, it shoud have been read "Any sex I had had ....".
That's why I confused a bit.
Is this kind of mistake or omission common among native English speaking people or just among uneducated people?

Phoo..I'd call this an omission...the sentence you quoted would be how a majority , if not all, native speakers would have written it. The quote obviously has come off a novel or something like that, not from an uneducated source.

Thanks, I've leraned!
