My parents fucked to have me.

Vs:

My parents had sex to have me.

Or even:

my parents were on the bed doggy style, when my mom was on hands and knees on the bed while my dad was behind here thrusting his huge penis into her very tight vagina over and over. She loved every second of it and so did he. They loved eachother very much and entrusted eachother enough to allow this raw behaviour into their bedroom each night of every day. As the penis reached climax, it injected billions upon billions of spermatozoids into her vaginal cavity. Each sperm only had one goal.... Swim, swim! If the egg is encountered then go into it to inject the DNA that would become me. All but one would encounter they demise.
