Problems after Outing with my parents

So Ive outed myself to my parents (yay) and we had some talks about me being trans and what to do. We already made an appointment at my doctor, where my parents wanna talk and get tonknow more from the doctor (I think?). My problem currently is, they still think the internet told me Im trans and stuff and that some experiences are "normal" to them, like being uncomfy durin 1st and 2nd grade when Im topless. I dont get what they think I mean, I hope u get what I mean. What should I tell them, so theyre not confused/worried anymore, so they dont think its some sort of influenced thing?
