A more thorough explanation:

Definition: Sexual relations refer to physical sexual activity between two people. It can involve sexual intercourse or other sexual activities that do not necessarily lead to intercourse. Examples of sexual activities include touching of breasts, vagina, penis, or anus.

For instance, when two people engage in sexual intercourse, they are said to have sexual relations. Similarly, when two people engage in other sexual activities such as touching each other's genitals, they are also said to have sexual relations.

It is important to note that sexual relations involve the consent of both parties. Any sexual activity without consent is considered sexual assault or rape.
