What's The Punishment For Wasting Seed And Intermarriage in Judaism?

What is the punishment for wasting seed and intermarriage? King Solomon tells us in Proverbs chapter 31, Don't Give Your Strength To Women. The Sages teach us that this is a warning against the damage caused by wasting seed. Gehinnom has seven chambers, each worse than the next, but they all end at some point. Except the Seventh Chamber, it never ends, it's a place of eternal suffering. And intentionally wasting seed is one of three sins that lead to this chamber in Gehinnom.
