In general, the rates of incest are significantly underestimated. I have seen this anecdotally with the individuals myself and friends have dated, along with volunteering for sometime with CPS here in Texas.<p>It is unreported for obvious reasons, and few realize how easy it is to get away with. Families have lived in close quarters for a long time, and the opportunity is great for sexual gratification with another. Siblings often live in the same room. There are significant power dynamics at play when one sibling is 3 and the other is say 11. Yet there aren't the restraining forces of maturity on the 11 year old.<p>Sadly, the incest movement was probably set back 20 years due to its association with Satanic Ritual Abuse in the late 1980's and 1990's.<p>For those looking on help with this, I highly recommend the book "Courage to Heal" by Ellen Bass [1].<p>A sign of progress is that in the latest editions of the book, it also focuses on men. The early editions only focused on women.<p>[1] - <a href="https://www.amazon.com/Courage-Heal-Survivors-Sexual-Anniversary/dp/0061284335" rel="nofollow">https://www.amazon.com/Courage-Heal-Survivors-Sexual-Anniver...</a>
