Every time after a ONS or casual sex encounter I just feel hollow and empty. It feels quite nice while it's happening but afterwards I just feel an emptiness.

It also just feels like a huge waste of time/effort. I feel like I could be putting this time, effort and energy into investing in myself - I go to a top university and see opportunities to network, to read books about investment/finance, to explore hobbies, etc. All of this seems much more meaningful and satisfying than ONS encounters.

I love life when I'm going gym, hanging out with friends, investing in myself, studying, exploring my hobbies, meditating, etc but once I have a ONS I feel a lot emptier/shitty. Is this a sign that I desire compansionship/LTR?

Does anyone else agree? Is it normal to feel this way? I am only 21 years old yet I feel like ONS/casual sex is massively overrated.
