My grandmother had her first child out of wedlock at the age of 14, her second child (my mom) out of wedlock with a different father at the age of 16, and her third child out of wedlock with yet another different father at the age of 17. And this was all in the 1930s. I strongly suspect grandma really enjoyed the sex -- otherwise, why go through all the social approbation and abandonment by her family that went along with it?
