It is the beginning of potential life, and using a condom is the denial of potential life, as is a woman avoiding intercourse when ovulating.
The point that is usually ignored by one side of this debate is that there is also always another life that is well past the potential stage, namely the woman.
I am afraid you are mistaken. Copulation is the beginning of potential life. When the egg is fertilized, life begins. You seem to understand this because the second part of your statement is all about preventing the fertilization of the egg.
