I am 26, and I still find it very hard to pleasure myself, I cum after one hour, never had orgasm

Hi I'm a female I'm 26 I've been having sex for 10 year now and I still find it very hard to masterbate and cum it takes me over an hour and i have never had an orgazam I've never had a guy make me cum sometimes when i do have sex I get close to cumming but then I lose the sensation and it goes away also when I am having sex or getting fingered I will get very wet but then I dry up and it gets very annoying and embarrassing please help thank you
