Asexual Life

Hello, recently I found out that I am Asexual. I didn't even know what it meant. I have never had sex, nor have I ever been attracted to anyone in a sexual way. Me & my partner live day to day not having sexual feelings, but we are both happy. I feel things towards men & women, but don't want to have any relations, don't get me wrong, I enjoy masturbating whenever I can, but I feel dirty afterwards. Is this just me? Is there anyone else out there who feels this way?
