Hi there Prettypaws, and welcome to the boards!
I’m sorry to hear you’ve been having trouble finding your clitoris — I know this can be really frustrating to try to find it and realize your anatomy looks different from typical diagrams. But if I can reassure you at all, there’s no one way a vulva is “supposed” to look. In fact, while the clitoris is typically sheltered by some skin, plenty of folks have a smaller clitoral hood or even a less protruding clitoris — more of an “innie” than an “outie” if that makes sense (using belly button terminology). Also, some folks do find that their outer labia is much bigger and covers the inner labia, which can be revealed by gently spreading the outer labia apart with your fingers. Here is a great article we have, too, that goes more in-depth on the clitoris and how to find yours!
Innies & Outies: The Vagina, Clitoris, Uterus, and More!
When you use a mirror to find it, have you tried exploring with your fingers to pull back those pieces of skin and see? I ask because your experience of sensitivity to touch in that area, plus the vibrator hurting, does indicate that you probably have a clitoris because you are feeling sensation there. Too, I’ll add that the clitoris is much bigger than just the external head, it actually goes inside too, and the majority of the clitoris is actually on the inside of your body! So, my guess is that you may have a smaller clitoral head, but you indeed have a clitoris to explore.
I’m sorry to hear, though, that it’s been difficult to find pleasure masturbating. It can be really tricky sometimes to figure out what works for you, and you’re not alone there: plenty of folks do find that they go through a process of exploring many different erogenous zones with different techniques before finding the most pleasurable way to masturbate. You can see in
this article that there’s a multitude of ways folks find masturbation pleasurable, and it can take some time to find which way works for you. Some things that can make this exploration a bit more fun and pleasurable include making sure you're relaxed and aroused, using lots of lube, and approaching any exploration you do with curiosity and appreciation instead of with judgment and expectation. Those things can all go a long way to getting us in the right headspace for pleasure, “setting the stage” as it were.
Also, when you say you’ve grown up only being able to rock your legs etc., were you able to feel pleasure with those activities? Plenty of folks do find that they enjoy a grinding sensation more than laying on their back and touching directly, especially if their anatomy is more sensitive to direct touch. If those activities felt good for you, exploring other ways to produce that sensation of rocking and compression might be a good place to start! The article I linked above,
Going Solo: The Basics of Masturbation, has some great information on how to explore these sensations.
That was a long response, so I’ll stop there: how are you feeling about all that?
