Does kissing 6 guys by age 15 make you a *****?

I mean... I don't get it? Like... Four people were like "OMGZ UR SUCH A *****, YOU KISSED 6 GUYZZZ OMGZZZ!!" IT's almost stupid. People don't seem to see the difference between a kiss and sex, why? I only kissed 6 guys and I already get labeled of something I am not?? Or is my perspective of reality distorted and, indeed, kissing 6 guys make you a wh*re, even if it was at different times and one of them is now my boyfriend?
