I want to be a swinger but my fiancé doesn’t know.

How should i tell her without her leaving me?

You can't really control her/other person. And you shouldn't actually try, if it has anything to do with ethics or love.

[MauroDraco]

But, if the worry is real and love and ethical behavior are on, then, you don't need to tell her; that is, you can choose to not do it simply.

Or you can have an open conversation about it, without demanding or expecting a particular outcome.

I get the impression she has expressed no interest in swinging, sleeping with others or wanting/watching you sleep with others, which, if that's the case, you are asking us basically how you can convince/manipulate her to let you fuck other people without her dumping you

[CopperKnob]

You have a grown up conversation where you discuss your wishes and then you listen to her views. The pair of you then decide what is acceptable for each of you.
Doing it without telling her is cheating and I would suggest the exact opposite of being ethical.

If you really want to approach the subject with her in an ethical and decent way, you could maybe see if she likes some related porn? Or just speak to her, you should both be able to be completely open about that sort of thing, it will make you a stronger couple.

Just be an adult and say its been on your mind to try. Like a big fantasy. How does she feel about it. Will she be ok to let you try it ir even better... try it with you?
You wont know where you can progress to unless you talk honestly. Bo manipulation or coercion. Just say it as it is and compromise

It depends.

If you're able to say to her - look, this is something I want to try but if you aren't open to it then obviously you're more important and I won't mention it again - then if she respects you she won't really have reason to leave you.

But if you're planning to do it anyway regardless of whether she's receptive or not, then she'd be right to be leaving you.

She's your fiancée, you have to be fully open with her in these matters. If you can't, you won't last.

It's a chance you take. Some may shut down completely. Personally I don't see it as a situation that I would willingly enter into. I will not share. Period.
