Wife enjoys Roleplay

Hi I am saad (37) from Pakistan my wife name is Sara (37).

We both were in sexless marriage for almost 9 years. When so ever I used to ask Sara let’s have sex her reply would be I don’t like Sex. Then one night we had a detailed discussion in which sara said she doesn’t like sex because there’s nothing new in it.
Note: we are conservative
So I started searching on Google, about new things in bed, from there I came to know about Roleplay. Long story short we started roleplaying in bed. She said she will remain her and I will act as someone else. She started enjoying sex and it was like the best sex of my life.
How to ask different questions which I am facing right now.
