Expression: 'You need feel under...'

[Tom]

Hi

Could you please elaborate the following sentence to me?
I mean, the bold part/ structure. Does it sound OK to you? If so, I would request (for) a few more examples.

1- You need feel under no compulsion to accept the rules.

That's an odd sentence, Tom.

I'd prefer the word obligation to the word compulsion.

But the logic of the sentence seems odd. Are you trying to say that there are rules that apply only to some people (but not all)?
