It is a must you understand your safe days and understand your ovulation. I really don't know why girls don't care much about this. My girlfriend doesn't care about it too, and that's why I have a vast knowledge about this subject because I read lots and lots of articles and watched lots and lots of videos. I'm can tell you, with this method, you can enjoy the pleasure of unprotected and don't get any scare of pregnancy.

Note, you have to practice this method with your partner alone, because there is STDs and HIV out there. Because this method has nothing to do with HIV and STIs & STDs.

I know the video is long but if you watch it, you would fully understand the calculation and I'm here to answer any question that you may want to ask.

Thanks for coming around and making such a nice comment @oluwatobiloba
