What should I be careful of when starting my "breeding" task?

Hello everyone, I recently found this sub and I wanted to ask if anyone could give advice on what to watch out for when I'm going to try to start my breeding mission with a female friend? <br><br>I'm 22 years old and my female friend is 20, we've known each other for a year and we're close friends. And we live in a country in Europe.<br><br>Thank you for your time!<br><br>Edit: I'm not a brood stallion. I think I should try to have children in order to understand what I have done to this world and to understand the meaning of life.
