My thought is most women answering this are going to say "NO FREAKIN WAY", while most guys are going to say, "Yeah, why not", (unless they find out she means M M F).
What Would Be Your Answer to Your Husband or Wife,if they Bring Up the Subject of a Threesome ?
I have tried it a couple times and I know it is not for me. It does seem like a last ditch effort to stay together but who knows, for some people it might be what they actually need. I know of a girl who lives as a throuple (two guys, one girl) and it has been working for them for a few years now so each to their own...lol
Depending on the state of the relationship I might want to consider a M M F.
But I don't think that's what most man will have in mind when they suggest a threesome.
I'd wanna know his reasons for wanting sex with another woman present. Generally a man cannot even fulfill one woman, so why want two?
Honestly, I think it's the death of a relationship, unless both feel very safe and secure with one another and have solid self-confidence etc.

Spicing up things makes the relationship less boring
If you feel that way it's time to have a good talk with each other, and possibly leave the relationship. When feeling this way it may be dead already, you just forgot to bail ship when it went under.
