We did ICI in March and had our healthy baby boy Dec. 7.
Here’s what we did: found a super good friend we felt really comfortable with, tracked her ovulation cycle, ordered needleless syringes and preseed lube from Amazon, and tried as much as possible during her ovulation cycle.
The cliff notes: we tried our best under the circumstances to arouse her beforehand; he orgasmed into a non-spermicidal condom; I inserted the preseed lube into her; I used the syringe to then immediately plunge the ejaculate out of the condom and into her, as quickly as possible, and trying not to expose it to air; then we tried our best for her to orgasm; then she sat with her legs up while baby daddy and I had some uncomfortable cups of tea in the kitchen.
We seriously tried everyday for like five days, and sometimes twice a day (baby momma and baby daddy are troopers). We know we are lucky and it’s unusual to have success with the first try, but it did work! Let me know if you have any more questions. Below are links for the exact materials we used. I’m sure you can buy smaller amounts of the syringes elsewhere, but at the time of purchase we weren’t feeling optimistic.
Good luck!
