Virgin!?!?!

Hi, im a 14 year old virgin, and im really scared to have sex, i dont know why, but i just have that fear.

For example (if this helps) in health class at my school (since im in 8th grade they go into more details) i couldn't stay on the class cause it made me really nervous.

So my questions

are-is this a normal fear?

Do you think i will change?

And did anyone else have this fear?
