So I Married Two Aliens by Lyonne Riley

What’s a girl to do when she’s looking for true love but can’t seem to find it on Earth? She applies for an alien husband, of course!

But when Fiona receives two for the price of one, both of them decide she’s their fated mate. Saddled with this “clerical error,” the soft-spoken Fiona has to help her territorial alien husbands get along when all they want is to tear each other apart.
Shathar left his grocery business behind to find a new life on Earth—and a bride he could love and call his own. But now he must compete for the title of Fiona’s husband when all he wants is peace and happiness.
Khesan came from a wealthy family and a strict military life. Knowing he’s found his forever in Fiona, he’ll use all his drive and determination to show he’s better than Shathar and earn her love.
But only one of them can stay, and it will be up to Fiona to decide who. How can she choose when sparks start to fly between all three of them?

This is a sweet and spicy M/M/F rom-com (with a little bit of angst) about two aliens looking for true love, and the woman who can’t choose between them. You can expect fun peen, lots of steam, alien hijinks, and a heartfelt HEA.
