That’s true. For a bisexual male, >90% of his dating pool are women. And it’s more socially acceptable for him to be with a woman. Plus, women can get pregnant. Even if adoption and surrogacy are both legal in the country he lives in, they are expensive, time-consuming processes. So naturally, most bisexual men will want to have wives. But there are bi men who are open to marrying/cohabitating with another man, or would prefer to marry or live with another man. If he’s a single father and doesn’t want anymore kids, or if he has a demanding career that makes fatherhood difficult, I'd say he’d be okay with marrying someone who can’t get pregnant and wouldn’t mind a husband or boyfriend. In which case I’d definitely be more likely to date him if he wanted to date me.
