I need a break, have two girls already, but my wife won't even let me use condom. Please how can I prevent pregnancy without her knowledge, like the use of drugs. I don't want to castrate myself yet, I fit change mind later.

Cut it off.

Why not do a vasectomy?

Don't take me seriously but realistically it's an ideal method for your situation.

Is wifey, hoping for a 3rd child and a boy? If that's the case and you're truly okay with your 2 girls, assure her you are.

Some women don't feel secure/comfortable in hubby's house if they haven't birthed a male child yet. So, give her assurance (not the kind David gave Chioma please)

Alternatively, you can remind her that in the event of your demise or job loss, 2 kids will be easier for her to take care of than 3.

I don't wish you any of those life events above, but they are a reality of life we often like to shy away from.

And please I don't get how you want to shag with a condom in a marriage relationship. I don't blame wifey for disagreeing to it.

The bolded is simple truth.
Yes, she really needs a boy, but I am the six male in my family so that's no issue for me at all.

Vasectomy not equal to castration?

Thank you for your genuine advice.
