Would you consider seeing a professional? Like a Certified Sex Addiction Therapist, in order to fully understand what's normal 24-year old sex drive and practices, and what might be problematic thinking and behavior that would lead to addiction or other ruin?
I personally benefitted from Dr. Ralph Earle's book Lonely All The Time - very helpful to help me understand why, no matter how good my personal relationships, it was never enough. You might also benefit from the community at r/SEXAA - lots of people struggling with the same questions as you.
Hope you get things sorted out and put these worries behind you.
