Like I said before in my prior post... if you've already paired with someone, and you've reached the number of offspring that you're good with, you should TOTALLY just get it done.
REMEMBER: Birth-control meds for the women, though they are much better these days, have an increased risk for them to develop a thrombosis (blood clot) which can then dislodge and migrate within the circulatory system, and when that does occasionally happen, it's an extremely serious situation. If that clot ends up getting wedged-in and stuck somewhere in the circulatory system that is vital..... brain.... lungs... heart... irreparable damage or death can occur.
Back when I was young, late 80's into early 90's, a co-worker died of a thrombosis she'd developed as a result of the BC Meds. In her case... the clot migrated and got stuck in a major artery that supplies the lungs, and that was it, that's all she wrote. Bye-bye.
SO... if you are certain you don't want the chance of making a kid, and are in a committed long-term relationship, it's also something you can do to make things safer for your woman, so she doesn't have to take BC Meds anymore.
NOTE : Some women are prescribed BC Meds on purpose. Like if their periods are erratic or unusually heavy. OR, sometimes, if their production of Estrogen is on the high side, and that estrogen leads to a more rapid growth of fibroids in their womb, they might Rx them a BC Med in regard to that issue. Do with that info what you will.
