Notice how imams are not celibate like Catholic priests. In fact celibacy isn't even a thing in Islam. You're actively encouraged to get into a relationship and get married so you can fulfill your sexual desires. There's even a prophetic quote that says getting married is half of your religion. It's that important. Of course some things like drinking is not allowed even if you desire it and that's just something you have to deal with. But even if you cave it's not the end of the world because the grading system is heavily curved in your favor.
Having desires is natural and human and it's even ok to indulge in them every once in a while in a healthy way.
The Islamic term for this is nafs which means "self" or sometimes "ego". So fulfilling human desires is filling your nafs. But just like overfilling your stomach can be bad, overfilling your nafs is also bad so you need to practice discipline in not getting carried away.
