Hookup asking about past relationship?

I met this guy via dating app. We hung out then back to his place. After we did it, we cuddle and out of the blue he started asking questions about my past relationship. I answered half heartedly because tbh I dont feel comfortable with the question. Is it normal to ask? Tbh I dont have many hookups, so I am not really sure what to expect. Having perspective might help.
