Men enjoy porn. It's the visual stimulation that gets them excited and makes them feel in the mood. It doesn't need to be something you do by yourself though. You could certainly invite your partner so that you can add some spice to your sexual life and perhaps elevate it to a whole new level. It is not necessary to keep your porn movie secret. This could lead to arguments and mistrust if it gets discovered by your lover. It's best to discuss it with your partner to see whether she is keen to watch it along with you. It won't be considered a "dirty secret" and you'll be able to have fun with your fantasies.
In the discussion of whether watching pornography is okay there is no best or worst answer. There is nothing wrong with watching pornography as long as it is legal and everyone is agreeing to it. If a person chooses to binge watch porn rather than be intimate with a partner who is interested, it could cause issues. The issue is more about the relationship than the content. According to research on the online behaviour of people, those who engage in sexual activity for less than one hour per week had very minimal impact on their lives. If the exposure to online porn was more than 11 hours per week, respondents claimed that their behavior could impact both their self-image and feelings about their partners. It is possible to tolerate between one and 10 hours of porn online per week, however it is not acceptable. This could be a means to reduce anxiety.
