Hello there, fellow non-masturbator. I am (cis)male and do not masturbate, I don't have any desire to masturbate. I thought for a while that I was asexual, but found that not to be the case after i lost my virginity. This could be the same for you, or you could be asexual. I would encourage you not to identify as anything until you are sure. If you want to masturbate, do so. If you want to do it but don't want the guilt, then therapy may be an option. If you don't want to do it, don't.
