lack of feeling....great? is there something wrong with me?

Okay so maybe about three months ago I went to Spencer's and bought a vibrater. I want to learn more about my body and how it works when being pleasured. Well for months I been using it or at least trying but when I use it I really don't feel anything. Nothing that makes me feel so good that I want cum or anything. And it's kind of making wonder if there's something wrong with me or maybe my body is not meant to feel pleasure. Anyways do anybody have any ideas, stories, tips, or advice they want to give me on why I might not be feeling pleasure? I never had sex before FYI, so it's not like I have much to go by. I will really appreciate the responses and knowledge from you great people. 😊 Thanks!
