I have been fighting with over-consumption of long-hair photos and videos since 1994. It makes my wife said, especially if she finds out that I have contacted cam girls. The following advise have helped me quite a lot - allthough apparently not kept me totally out of sites like this one:
1. The most important advice: Devote your time to a meaningful spare time interest that attracts your attention for a while, or to hard work! It may involve social interaction with people and it should be something you think is important and/or really fun, for example with your family or friends on a regular schedule.
2. In case you devote too much time to Internet photos and videos, install a filter software (a content control software). It stops access to most porn, but you may also configure it to filter search for "long hair" and also stop certain non-pornographic sites that you devote too much time to. Randomize the password with your eyes blind folded, print it out and save it in another building. Or ask a friend to store it for you and check your loggs reularly. (Such tools helped me for several years. However, I work with computers and I have access to many computers so I have found ways to get around the filter.)
3. In case you often pay for stuff on the Internet, cancel your credit card and ask your bank for a more simple payment card, for example intended for teenagers, that would not allow you to make Internet payments.
4. Get involved in a self-help group of people with similar problems. For example slaafws.org/ . (My problems are related to procastination so I wanna meet more people with those problems.)
5. It is better to quickly masterbate without watching porn or long-hair photos, or even better to have real sex in a long-term relationship, that to devote hour after hour to searching for arousing material on the Internet.
