How can I make my partner say yes to threesome

So my partner (33M) and I (24F) have been together for almost 2 years. It’s not a perfect relationship but our sexual preferences or kinks line up with each other. He’s had ffm and mmf threesomes before which made me envious. How can I make him agree to a threesome with me?
