I don't know if this are available here or whether you could try some of this-
1.Reversible inhibition of sperm under guidance(RISUG)-consists of injecting styrene maleic anhydride in dimethyl sulfoxide into the vas deferens and leads to long lasting sterility. A second injection washes out the substance and restores fertility.
2.Vas-occlusive contraception-unlike vasectomy which removes a piece of each vas deferens, this blocks the tube until the plug is removed.
3.Papaya seeds-papaya seeds have been found to completely remove the sperm from a male monkey's ejaculation. Rats have also been tested with a compound from papaya seeds and found to have "significantly reduced" sperm counts. At higher levels of ingestion, the rats became completely infertile. The rats' researchers then declared the long term, daily use of compounds from papaya seeds to be a safe and effective male contraceptive.

4.Hot water-It turns out that sperm don't like heat and by bathing, or simply submerging the testes, in 116 degrees water (just below the pain threshold) for forty five minutes each day for 21 days, a male becomes sterile for the next six months. Doing this at 110 degrees reliably produces sterility for the next four months and either way, it can be repeated for continued effectiveness when the allotted time is up. This method dates back to the writings of Hippocrates and derives its effectiveness from the fact that sperm needs to be several degrees cooler than body temperature to be viable; this is why they hang outside the body. Actually, sperm cell death happens at 95 degrees F, while normal cell death happens at 108 degrees F - so this method effectively kills the sperm for a limited but extended period of time.

@ Selah, if you want to go the devout Catholic way, then even your wife shouldn't use contraceptives n u shouldn't use coitus Interuptus (sp)
You should only use natural method.
Did I read up there that what you should has other benefits so u don wanna c em go down the drain? I think this is rather secondary u can pass on the same. I also think you should get more involved with are we safe to do this tonite/today? Don leave it to mama alone. Two heads will be better than one and with the right coaching then you will reduce substantially chances of unplanned tois. The problem is tat some people have irregular cycles but I guess the training will iron that out.

Holly shot! you have never used a condom and you know how to use internet? Did someone said Catholic do not approve use of birth controls? Maybe I missed the bus but do we also have to ask the change how to sleep with our partner? Holly shit!

kuna kitu inaitwo coil, jaribu hiyo

I must say these are certainly not conventional means. Ati submerging my balls in hot water for 45 minutes for 21 days?

I'm also not cool with injecting stuff into my vas deferens
