Salam moulanathank you for the replymoulana can the couple talk about their past sexual lifeand also their fantasy it will remain with them only both are ok with itthen what's the problemcould u give a reference as it not allowed

wsalam,
there is not everything with reference, Allah Subhnatala give us brain to think and decide wat is good or bad,
while talking abt past with someone else breaks the Haya and definitely to whom a person talk might living their own life plus in past they made any prohibited things so better to astagfar neither to tell each other
.
I consider past before marriage
