There are people in the world who are eager to experience their private sexual fantasies, and they may choose to leave a partner who will not indulge them. They have an inherent belief that there is someone out there who is willing to do what they want, and they choose to find this person. They may have become obsessed with their fantasy life, and the relationship would not be able to survive their demands. It is best to break up with this type of partner, and this allows each person to pursue their own lives as they see fit.
Finding a partner for casual local sex is often a fantasy of many, and they can now find someone online to satisfy this sexual dream. Rather than develop a relationship with the person, they see this is a one night stand with no consequences for either partner. This is a recurring fantasy for many, and looser cultural restrictions on intimate behavior have made it easier to fulfill in the modern world.
People who want to skip the relationship but keep the same partner will be able to turn their fantasy into reality with a fuck buddy. These are people who acknowledge the fact that they are seeking only physical encounters with others, and they want to know as little as possible about their partner. Fuck buddies specialize in being available for sex only, and they have no illusions their current partner will form a permanent bond.
Few people are willing to leave a relationship where a real person satisfies their intimate needs, but some of them are determined to act out their fantasies. The availability of people to help them has risen as society changes, and they may find what they seek with a simple online search. As for their partner, perhaps that person will also find their own dreams come true when they find someone who wants reality instead of fantasy.
