Thing is, I don't think there's a single instance where porn can have a net positive affect on ones health. Could be wrong, but I doubt it. Best to just pray about it and force yourself to try to get a wife.
You can repress your sinful urges, but it would be better to get help from a pastor or other religious leader. Preferably you should also form attachments with strong men who can show you what the real responsibility of men means to you, and how sexuality is only a very small part of that identity.
