What a sample holds
Value enum
HKCategoryValue — the enum Apple’s page for sexualActivity names: the generic one, not one of its own. Every category type’s enum is on the HKCategoryValue reference.
Aggregation style and unit family apply only to quantity types. For a category type the dataset records neither, because the concept does not apply — not because Apple declined to say.
Can apps write sexualActivity?
Apple’s documentation for sexualActivity does not state that its samples are read-only. Apple states read-only status only in prose, and its silence is not a statement either way, so this page makes no claim that apps can save it.
On Android Health Connect
No verified Health Connect counterpart. The cross-platform matrix pairs only metrics checked against both Apple’s and Google’s documentation, and sexualActivity is not among them. A similarly named Health Connect record may exist, but a name match is not a verified mapping.
