I am sorry to hear about all of the coffing.
1. Don't try to hold it your coffs, if you do you will end up pooping in your pants. If this happens during sex, it can really be a mood killer. This is real, and something you don't want to experience. Just let it out.
2. When coffing after your husband has ejaculated, just have him scoop up his swimmers with his hands that have been pushed out of you. You can then put them in a turkey baster and put them back where they belong.
3. Stay in bed, on your back, for the next 2 weeks. This is the only way to ensure that coffing will not prevent your baby from planting like a garden in your ute.
