What should i do now that i like girly pop music?

sooo for a couple years when i was in highschool, i was really into /metal/grindcore, but after highschool i heard stuff like jojo and hilary duff. ever since then, i've been getting into more and more pop, and can barely stand the heavy stuff! i listen to other stuff like natalie, demi lovato, esmee denters, paula deanda, tynisha keli, and miley cyrus.. i feel strange listening to it around people so i never tell anyone i like this stuff cuz theyll probably make fun of me.. how do i tell people about this? my family thinks im still a kid who listens to people screaming... i dunno what to do!!!
