ELI5: Why do some orgasms feel amazing and others really weak?
gpt
Length of time between orgasms, level of arousal, length of time to achieve orgasm, hydration and general focus are all factors in good or bad orgasms. 

Abstaining from masturbation/sex for a few days can make for a great orgasm the next time you decide to do your thing. 

For men specifically, hydration can really help with seminal fluid production, causing more contractions to ejaculate a larger amount of fluid and a more intense orgasm.
