Hello and welcome to Healthcare Magic. Thanks for your query.
You are unlikely to get HIV
by sharing a bong. HIV spreads when there is exchange of the following he body fluids which contain high concentrations of HIV:
-other body fluids containing blood
So, there is no need to be worried that you could have got HIV through this. But in the future always be careful - always practise safe sex
and never share needles.
Wish you all the best.
