I think the real issue in that story was the treatment of the wife and the husbands refusal to let her have a child, not the spilling of seed per se.

This would fall under sex outside of wedlock and bringing life into the world without providing the fathering that was meant to be.

Correct: Genesis 38:9-10.

However, the rationale is comparable.

God created Adam & Eve (men & women) with natural laws to pass down to their descendants.

Medical manipulation and lasciviousness have destroyed those golden rules.

Incest by proxy, adolescent promiscuity, revolving shack-ups or multiple ‘marriages’, lack of male parenting and homosexuality are all contributing to the destruction of a Godly society.

One note on the Onan story, that "wife" you speak of was his brother's widow and under Law he owed her a child that would be called his brother's. He was struck down for repeated disobedience because any child with her would not be known as his.
