I agree with you 100%. There are enough anecdotal examples where men have not followed through with personal examples and women's friends personal examples.

But the author's view that it is reversible is not exactly honest or true. In the studies, I have observed, only 10% of the population executes the reversal and the 5-30% range is seen. My guesstimate is the failure rate will be larger.

One other aspect to think about is, if a person modifies their body for another it has to be fully consented to. The feel and intent of the author in the discussion doesn't "feel" (and this could be my reading it wrong) like that.

So if he steps up and gets snipped and does this for the relationship, then he has made a huge contribution to her safety and happiness. At this point, if he has any concerns about quality and quantity of sexual intimacy, she will have to step up since he altered his body for her choice and needs.

If she doesn't ... well his worst fears have come true, and what is worse is if the relationship ends and he is with another partner that desires a family he has been scarred for life and will also lose out.

The other angle is sex is more then penetrative sex between a man and woman. IMO, that is a very penis centric view on life, and while I have no doubt that quite a few women take great enjoyment in this, there are a lot of things that can be done to widen the intimacy out of this.

E.g if for 6 days on either side of the "peak" fertility, the guys learns to pleasure his partner fully sans "release" in her, and the engage in this more when it is safer with protection, game on. Everyone can win. One of the support items for the intent I referred to earlier is saying how it doesn't feel good if he wears a condom during sex. To me that says there is a huge mental component outside of the "pregnancy" aspect that needs to be investigated.

This is at least my view on it. As for male birth control, simple things can be done to prove to the female partner it is being done. E.g. showing her every day you are taking it in person. That is something simple and small that could be done to help increase the safety of the intimacy at zero to no cost, and given time trust can be had.
