Other than condoms, birth control (used mostly as birth control, not as menstrual regulation) is mostly relegated to trusting long term relationships already: STDs exist. So whether this is better or worse than the pill for women engaging in casual sex is probably not all that big of a deal: If you are trusting someone's recent STD panel results, you are still putting quite a bit of trust in them.

Now, saying there are better options in those long relationships is quite the claim. There's a non insignificant percentage of women that have serious side effects with hormonal birth control: Mood changes and reduced sex drive are crippling, if you are unlucky enough to find yourself in that category. Surgical approaches aren't great if you see a possibility of wanting to change your mind later.

So there's definitely a market for male birth control, if it has few side effects. Will it sell as much as once a trimester hormonal treatments for women? probably not, but you are assuming there's no market there.

absolutely agreed, If there are pills and procedures for both sides, whoever has bad side effects (or risks for a surgery) can opt-out, and the other partner will do it. Or both can combine, decreasing the risk of pregnancy even more
