What indicates whether a person is currently sexually active?

The indication of whether a person is currently sexually active is best reflected by their own account of their sexual activity. In this case, when someone denies engaging in sexual activity, it is a clear and direct response regarding their current level of sexual activity. The individual is stating that they are not participating in sexual encounters at all, which is definitive in determining their current status as sexually active or not.

Other choices may speak to aspects of sexual activity or relationships but do not explicitly confirm current sexual activity. For instance, denying a relationship might inform about romantic involvement but does not clarify sexual engagement directly. Reporting weekly or occasional encounters implies activity but does not provide a comprehensive understanding without context about their overall sexual behavior or current relationship status. Therefore, only the denial of sexual activity gives a straightforward answer regarding whether the person is sexually active at that moment.
