Help a beginner?

I smoke cigars from time to time, and at the very least I enjoy the convo that goes with. I like some i don't like other, but i'm not sure how to figure out what i do and don't like. Was hoping i could get some advise on how to generally group them, ie. beer has porter, stout, pale ale, ect. and what the differences are.

also any general advise/tips would be welcome

thanks,
