Questions are good. This site is good too because of all the ages/experiences of "weird" things
Have you ever tried to masturbate or anything? The first time I masturbated I was 17 and it happened accidentally. I orgasmed and literally had to work backwards to figure out what had just happened; I'd never heard of orgasms, had no experience with sex, etc. but my little brain finally said, "Oh, I must have masturbated!" :-)
I would experiment on yourself

make sure you have all the physical "equipment". That helped me in the long run; I didn't get married until I was 39 and didn't have much experience before that but I knew all my "equipment" worked? So, I figured out it had to just be a learning/experiencing "problem" that I could get to enjoy/get "better" at if I wanted.
Another way of approaching what you are experiencing now, how would you feel about being an anthropologist? I feel kind of flat about that because it's not something I know much about or have had any reason to learn more about/experience? Pick something random like that -- how do you feel about broken noses? Yes, you can imagine they hurt from what you have heard but you don't have one (I got one Christmas Eve is why I bring them up :-) and there's really nothing in your life that you can think of that might bring you in contact with more personal knowledge at the moment.
