Vasectomies are meant to be permanent. Even if you get your vasectomy reversed, your fertility may never come back. Vasectomy reversal surgery is complicated and expensive, and doesn’t always work. So you should only get a vasectomy if you’re totally certain you don’t want to get someone pregnant for the rest of your life." - Planned Parenthood

Literally a five second google search will debunk your own point

Deformed jaws are another one.

1. male BC requires stopping essentially thousands of sperm, while female BC only requires stopping one egg from attaching. That's why female BC is physiologically "simpler".

2. risk is relative. For example, woman's BC risk is weighed against childbirth, because childbirth is dangerous. That's why women's BC has a relative advantage. Childbirth isn't something that men face, which is why men's BC has no relative advantage. That's why the bar for BC is strict with men. It's because the situations are different.

3. (related to point #2) trust and liability. If the man lies about taking BC, the woman ends up pregnant. The risk and responsibility lie on the woman.

4. the reason why the BC responsibility typically falls on the woman has to do more so with the nature of our bodies and how far people want the sexual process to travel.

For example, we could just make it so that every man wear a condom during sex. But there are both men and women who don't like that, because they want to "feel a more natural sex". Condoms interrupt the natural process right at the start. What's ideal is that as much of the process happens normally, and it is only stopped at the end to prevent fertilization. Following that logic, the sperm travels towards the egg and you wanna stop it right then before the end (for example, a cervical cap perhaps).

Women are on the receiving end of the sexual process, so if the couple doesn't want a condom, or if they want the sex to feel as natural as possible, logic follows that the "stopper-plug" would be in the woman, because the finish line of fertilization takes place inside a woman.

If the couple is ok with a stopper plug closer to the beginning of the race, just use a condom then.

I'll address your comment now.

Your first paragraph honestly comes off as quite toxic and bitter now that I'm reading it again. Everybody has bodily autonomy and the right to refuse anything, and the reason is irrelevant. You have 3 choices.

1. The woman accepts the BC,

2. the man accepts the BC, or

3. both refuse and just decide that you can't have sex.

You don't want female BC that's fine. Nobody here is shaming you for your choice. If you don't want it that's fine. But the same standard applies to the men you're choosing to date. If they don't want it, that's the end of that conversation. Move on to option 3. What you don't have is the right to scold or shame your partner because they don't wanna take something they aren't comfortable with. You should accept option 3 if the first two aren't available.

Yeah. I think you explained it well. The bodies themselves are different, so it makes sense why the interventions are different.

We could use male condoms, but the problem is couples don't like that because they want as much of the sexual process to continue naturally.

If you want the process to go uninterfered as much as possible, it makes sense to put the cork at the end of the race (right before fertilization).

If you're ok with interfering at the beginning, by all means use a male condom (put the cork at the start of the race).

Allow me to rephrase it then.

Everybody should have the right to refuse any sort of intervention.

Somebody offers you a medication or procedure and is like "here try this" you should be able to say "no thanks, I don't want it"

And that's the end of that.
