Answer:
firs start off with telling your dad that you noticed something wierd and you dont know how to explain it and you dont know if it's something natural ore if its a medical condition..and if he ask you what it is then you just take it from there...hopefully you dident do something you shouldn't have.. GOOD LUCK...
Go to your local clinic. Your parents dont even have to know and they base your income off what you make, or if your a student you are in a donation catagory which means you can pay whatever you have. But you should be talking to your parents, when your ready tho.
Parents are just people. Talk about it without getting emotional or defensive, and they will listen.
