That does not mean you are regressing. It only means you are human. Take all precautions to avoid homosexual pornography. It will seduce you, deceive you and destroy you. It will also eventually destroy your significant relationships.
Pornography is a pathetic substitute for intimacy.
You definitely need accountability. Take the risk to confide in one or two persons, admitting your temptation and confessing your actions. Ask them to hold you accountable by checking on your behavior at least weekly. Block your internet access to the porn sites. If you are a person of faith, you will find that prayer helps.
