This attained, so: can one get involved, cuddling female? (3,2,7)
I believe the answer is:
age of consent
'this attained' is the definition.
The definition suggests a singular noun which matches the answer.
'so can one get involved cuddling female?' is the wordplay.
'involved' indicates an anagram (involved can mean confusing or complex).
'cuddling' is an insertion indicator (inserted letters are cuddled or held).
'female?' becomes 'f' (abbreviation).
'so'+'can'+'one'+'get'='socanoneget'
'socanoneget' is an anagram of 'ageoconsent'.
'ageoconsent' going around 'f' is 'AGE OF CONSENT'.
Can you help me to learn more?
(Other definitions for age of consent that I've seen before include "Beyond which relations allowed" , "Time when agreement becomes legally valid" , "Legal majority?" .)
