What are your thoughts in terms of rules in dating?

i am 23. Whenever i date a guy, i want to keep it classy. hanging out and dinner first, movies, go for walks, kiss, then slowly move into the intimate stuff if we are on the same page and i can tell that he's into me. i always followed these rules because i dont want a guy to get the wrong impression of me. (even though it's hard to hold urges sometimes) anyway, my question is, if a girl were to give a guy a ******** before going on a date, would the guy automatically assume she's a slut? would he see her as "gf material" if two people were to interact intimately without going on dates and getting to know each other first? What are your thoughts in dating? I always played by the rules.
