I want to donate my sperm

Hello

It's not a joke and I thought about this for a few years. I read online how to avoid pay the child support, a legal way. I found a hetero couple and they agreed. We will go to a lawyer and do the contract. What do you think about that topic? I'm only 25 and do not plan to have a relationship, hence be married for a long time. But to pass away without passing my genes would make me depressed as hell.

Cheers
