Hi there,

Thank you for reaching out!

I am not knowledgeable enough about Australian law to say if this was illegal or not, but I can say with confidence that this adult's behaviour was completely inappropriate and incorrect.

A sensible adult would never speak to a four-year-old child about sex, let alone describe explicit content. Their behaviour with children (i.e. touching the bum) is also condemnable. It is natural to have concerns about this matter though many years have passed since. Are you still in contact with this adult? If so, it would be better if you avoid them altogether. If their behaviour has persisted and you're still a minor, you might want to inform your parent(s)/guardian so that they can take further action.

More importantly, I would strongly recommend you to meet a professional who will be able to guide you in managing your emotions with regard to this early childhood incident. If you're still in school or university, you can meet a school/university counsellor. If not, I would encourage you to find a therapist in your local area who might be able to help.

I have attached some links of some Australia-based organisations from whom you could seek further support:
