You've probably considered a yoga class once or twice—maybe your girlfriend tried to convince you—but for one reason or another it never stuck and you're still skeptical. Consider, then, one huge bonus of the practice you may not be aware of: it can improve your sex life.
I'm unfamiliar with the term 'stick in this sentence.
I guess 'it never stuck' means something like 'it didn't work out or succeed'.
I searched the meaning of 'stick in the dictionary,
and it has so many different meanings as a verb and a transitive verb and different usages, so I'm confused.
Can you tell me the meaning-in-context of 'stick' in sentence I quoted, and give me some tips or examples to make use of the term 'stick'?
I'm afraid I may not be able to master the term 'stick' forever.
