Sexual urges, what is happening and how to control them?!

I'm 26F, and these last two years my body has gone crazy... Is this normal? And how can I control this? Would regular masturbation help or something? It really makes me go crazy romantically speaking too 😅 like having weird fantasies and attractions for random people. So I would really like to control this better. I first noticed a big change after I stopped smoking... I've also been exercising a lot so maybe it's that?
