Dog dosen't lick me often, is she resentful?

So i've had the same dog for 7 years now and I know that she loves me but she doesn't lick me often. If I get hurt or im crying/upset, she'll lick me. If I pet her for a really long time, she'll lick me and if I buy her a new toy she licks me. Other than that my dog never licks me! All my past dogs licked me all the time. Is there something missing in my relationship with my dog? Honestly, my cat licks me more than my dog does! I have a very friendly labrador retriever doggie and have raised her lovingly for 7 years. Shes like my best friend but im just worried im doing something wrong.
