Final answer:
Characteristics of a sexually healthy relationship include being consensual, honest, and mutually pleasurable.
Step-by-step explanation:
The characteristics of a sexually healthy relationship are consensual, honest, and mutually pleasurable. This means that both partners willingly agree to engage in sexual activities (consensual), they communicate openly about their desires, expectations, and limits (honest), and they both derive satisfaction and enjoyment from the sexual experience (mutually pleasurable). As for the options provided, if all of these is an option, it typically would be the correct answer if all the other options are characteristics of a sexually healthy relationship. However, the provided information does not include 'all of these' as an option. Therefore, based on the information provided, the characteristics listed are part of a sexually healthy relationship.
