If a quadratic with real coefficients has two non-real roots, the two roots must be complex conjugates of one another. This means the other root of the given quadratic is $\overline{3+2i}=3-2i$. Now Vieta's formulas say that $s/2$ is equal to the product of the two roots, so $s=2(3+2i)(3-2i)=\boxed{26}$.
