Scared to go to Gyno?

Hey guys! So I'm 16 and I live with my dad (mom left when I was 11) and he does an awesome job at raising my sister and I! Anyways, I'm scared to ask to go to the Gyno. There's nothing really WRONG but I do have questions that need to be answered by a professional. I know he will take me but I'm kind of just scared overall. If I've never had sex or even had anything inside of me can I still go? That part confuses me.🙈 I need all the help I can get, thanks!
