How to stop being a desperate horny bastard? 23 year old male by the way

How do I stop THINKING ABOUT SEX AND GETTING GIRLS?? ALL I WANT IS SEXSEXSEXSEXSEXSEX AND GIRLS. I CANT THJNK ABOUT ANYTHING ELSEEEREEEEEEEE

PLEASE FUCKING HELP. I'm 23 years old and wrapping up this school year. Im struggling with motivation to do ANYTHING THAT DOESNT INVOLVE ME POSSIBLY GETTING SEX OR GOING TO THE GYM. If I go to class, I cannot focus and my mind wonders off. ALL I WANT IS SEXSEXSEXSEXSEXSEX AND I CANT GET IT SO I KEEP THINKING ABOUT IT. I know I probably have ADHD and dopamine addiction and I probably should get on Adderall but what are some other tips to cope with this issue
