He asked who’s the Best I ever had?

Been dating this guy for a couple months and when it comes to sex he does most of the work but I get so turn on every time that I wet the bed and he asked me who’s the best I ever had right after sex.. and I said him cause he makes me feel good and I asked if i have been his best and he didn’t reply.. now I feel some type of way, but why would he ask me that in the first place?
