I noticed that the girls who act a bit sluty or promiscuous ALWAYS have boyfriends and often innocent girls take time to get a boyfriend.

People are lazy by nature, and will pick the low hanging fruit. The girls that act... as you put it... slutty or, flirty... are low hanging fruit. This is to not say that someone will not see the value in you unless you act like that, but remember that patient and thoughtful people who will look further then the batting eyes and bouncing push up bras are the exception not the norm.1
