Maid of honor but no best man?

So my fiancé and I have picked out who we want in our wedding party. I’ve asked 2/3 of my bridesmaids, but he hasn’t asked his groomsmen yet. From the start, I told him I really only need my best friend from college by my side on our wedding day, but choosing just one person for him was too difficult (which I totally get, I have fewer friends than he does). I want to give my college bestie the title of maid of honor, but my fiancé is hesitant to choose a best man. Would it be strange for me to have a maid of honor but he forgo having a best man? At the end of the day, they’re silly titles, but I would still like to give out the designation.
