I got my husband to agree simply by using it. However, I am using it to conceive. But, maybe you could try to explain to him that the pill and patch, etc makes you sick (as it does to me) and that the condoms are very uncomfortable and hurt you. Tell him to imagine sticking his penis in a small rubber balloon but going in and out and in an d out without any lubrication, it wouldnt feel to good would it? You can tell him that I use this method and its been effective for me for 8 years, but now we are reversing it and ttc. Another thing is when you do decide to start a family, its harder with all of those hormones in your system and those hormones can actually cause cancer and breast cancer, etc. And even those hormones that ruin your body are not fool proof. Good luck
