Is you get tired of your partner. Its difficult to have sex with the same person again and again . Problem is, once you do it for a few times, you lose interest.
For women, even if they are not interested, they can do sex. For men, if they are not aroused and interested, they can never do.
Watching p0rn will help a lot as it removes the boredom of getting aroused by looking at your partner.
Many Indian women are against watching p0rn, but it helps men a lot.
