Porn like any other thing people enjoy can be an addiction but in that case it's bad as an addiction not because sex is icky (issues with the commercial porn industry notwithstanding). Also there are explicitly good ways to follow sexual desire that can bring you closer to people you love according to for example Christianity it's literally a divine urge (within certain contexts and with heavy caveats).

Also having sexual thoughts is part of being a normal person (not to say asexuals aren't normal). You're mentality reminds me of people who want to pray away the gay from themselves and it is similarly harmful to you to believe this tripe as it is for them to believe that there is something wrong with the way they are.

Put it this way I'm literally British and I'm telling you that you are too repressed. I've known Catholics who would be concerned with how much guilt you have over your sexuality and it absolutely doesn't make you a bad socialist socialism is concerned with solidarity and common ownership of the means of production not some perverse victorian idea of morality being when you wear cotton trousers all the time and don't think about sex, frankly with the stuff they got up to they have no business lecturing you about morality
