You're human, Allah doesn't punish us on our thoughts. It's normal for young adults to feel this way but I'm glad you're strong enough to avoid sin by never acting on it. That's real Jihad, daily battles against sin.
I'd say distract yourself with other things. If you're really busy or interested in other areas of life, this will be pushed to the back. Maybe start a personal project, something cool related to a hobby etc... Try filling up your time and thoughts with meaningful things like studying Islamic history, memorising the Qur'an etc...
Being closer to your deen means you are even less likely of wanting to harm it
