Have I lost my sex drive?

I’m 18m and I’m currently abstaining from masturbation for the month of November and am still doing so.
I’m doing this because I can never finish during oral sex with my girlfriend so I think I may have to retrain my penis’s sensitivity.
But anyway during this month I’ve noticed that I’m not really in the mood for anything sexual which is why I’ve made it this far into the month and any time in the past that I’ve done this it was really difficult to abstain because I was really in the mood so I’m just wondering is this normal when abstaining or will my sex drive come back at all?
