Human sexuality is a very complex and troubling issue.
Tackled by both the Kinsey Report and Masters and Johnson a few years back.
Both indicated humans are very complex animals.

Given my experiences up to today with life and other humans.
My feeling is that a adolescent is not an adult. Making life altering and sometimes irreversible decisions should not be allowed by them. Life threatening treatment of a physical nature is not included in this statement.
Like stated in the past. Known and seen many who have took many paths and turns down the road to adulthood.
Would you allow a eleven year old get a tattoo on their face?
