Isn't the point people can lie and we should all use contraception that we control until both want sex to result in a child
Abso.fucking.lutley.
Even from the perspective of the small but real chance of contraceptive failue, belt and braces ought to be viewed as the norm rather than "extreme measures".
I think that will happen to a greater degree when a non barrier method is available for men too. Say an implant, stick it in and bob's not your daddy for X number of years. (bar small statistical failure)
So female protected, male protected, and condoms are the forcefield against statistically rare calamity ...but mainly for protection against STDs.
In the meantime, I will keep banging on to DS about the only contraceptive he can be sure is being used appropriatly is the one he is applying to himself and using it exactly as directed.
And that if the worst happens, and a baby is made, it is not about him and it is not about her, it is about the child made who wasn't in that bedroom making any choices, and the smallest person had to be the over riding priority of all concerned.
Words cannot express how deeply disappointed I would be in him if he turned his back emotionally, phycically or economically on a child he created, whatever the circumstsnces of its conception.
And if he wouldn't be there in those terms, me and DH would be. Using his potential inheritance to make it happen.
