Kinsey's work was poor quality and suffered from irreconcilable volunteer bias. It was completely based on people willing to be interviewed, in excessive detail and in his uniquely invasive 1 on 1 fashion, about their most intimate sexual experiences. Even today that is not something which 'normal' people agree to, and this was done during the 40s and 50s! On top of that he made 0 effort whatsoever to obtain a representative sample of society, so it's a biased sample of a biased sample, which drives an exponential deviation from reality due to multiplicative biasing.

This is where you get his conclusions such as 37% of men having had a homosexual experience, or 69% of men having purchased a prostitute. It's plainly ridiculous.
