I can't orgasm..

I masturbate every once and a while, just using my fingers. I'm too young to go and get a dildo or lube or anything. I've never orgasmed, or at least I don't think. I've masturbated and pulled my finger out and there was some white and sticky substance, but I never had the feeling of orgasming. Am I orgasming? If not, any tips to help me orgasm? Please!
