Hi there, ItsJessica712- welcome to the boards! Don't worry, you'll be able to find it. I've put in a diagram of the vulva below for reference- if you place your hand on your mons (the upper part of your vulva where most of your public hair is) and move it downwards, you should find out outer labia. Just between them, where they split, you'll find the clitoral hood, with the clitoral glans underneath.
Touching yourself there might not feel all that interesting if you are not already aroused. Trying to get in the mood first may make the whole experience more pleasurable.
I should note that penetration should not hurt. Being aroused would also help that hurt less, as does being relaxed.
I hope this helps!
