A healthy, workable relationship is based on the interests, needs and comfort of both the persons involved. What you have shared gives a picture of what some of your thoughts and interests are. Now to what extent you can work out such a relationship would depend on who the other person is and what their beliefs and needs are. If they also find meaning and value in a relationship that exists primarily for sex, then it might not be much of an issue. However, if the other person has different beliefs, or is comfortable with a relationship involving something else or more, then you both might have a difficulty sustaining such a relationship. In short, these are things that the people involved in the relationship need to talk to each other about and understand - about each others' needs and feelings.
At this point, I am also wondering what your understanding about sex in general is. Human sexuality involves not just the physiological process of intercourse and pleasure, but it is a dynamic interaction of physical and psychological processes. It is often not possible to entirely separate the two. If you are looking to build a relationship "just for sex", I'm wondering what exactly it means.. what it is that you are looking for. Are you looking for a relationship that is free of psychological or emotional involvement? And if it is so, do you prefer all your relationships to be so, or just one, that you are looking for this way..?
These are some lines I invite you to reflect on, as these could lead you towards getting a better understanding of how you feel in relationships and what your needs and fears are. And if you need any guidance through this process, you are welcome to get in touch with one of the experts on the platform.
Best wishes to you in your journey to find and build fulfilling relationships that make meaning to you.
