I think “it“ is Sex Appeal abbreviated to SA and part may be your young as parturition is a term for giving birth. Can it be abbreviated to part?

[ProfessorMaisie]

SA for sex appeal/'it', is right and PART is 'interest' - the def is, 'My young had a tough upbringing' (Spartan youth had a pretty tough time).
