Of course, as our Holy Mother Church, speaking through the Holy-Spirit chosen Bishops, has often said, everyone does it, it's not fair to hold the Clergy to some kind of standard when it's such a common crime (or in the clergy's case, "mistake").  And yes, including 18 year old kids messing with 16 year olds is the same as an adult male abusing a 10 year old.  Its all the same.
