Erosion 

When a prude dates a non-prude and succumbs to the idea of some sexuality in their relationship, accidentally causing a sudden eruption of their own pent-up horniness. The word is derived from the lusty Greek god of love and horniness "Eros".

Wow, that prude's undergone some major erosion!
