There are many people that cannot find the right person easily. It takes them a great deal of time and effort before a compatible person comes along. They often end up in a series of relationships that don't work out. One reason this continues to happen is because they are physically intimate before both people are ready. Each person feels pressured to relieve their physical needs before really getting to know their partner.
People eventually realize what the problem is and decide they will wait until a relationship proves itself before they are physically intimate. This is a noble goal, but the pressure to find physical relief can often derail even the best laid plans. Finding a fuck buddy is one way to keep on track. Offering physical relief without a relationship is what fuck buddies do best. They have their own physical needs and want them satisfied. They are not interested in a relationship with their intimate partner.
Few people take advantage of this type of no strings attached sex. They choose instead to either derail their plans or resent the time it takes to really get to know someone. Choosing this path may take them a lot longer to find the right person. Rather than waiting for someone truly compatible, they may just settle for the next person they begin seeing.
It takes time to develop a good relationship. Even if both people are compatible, it does not always work out. Spending the time to find the right person and developing a good relationship will lead a person to a happier life. Having a casual relationship to relieve physical pressure while waiting to see how a relationship goes may be best for all concerned. It gives people breathing space to find out how truly compatible they can be in a long term relationship.
