I attended a lecture by Glynn Harrison recently on this vital (and polarising) topic. He brought a lot of wisdom to bear on the matter of how to respond sensitively as a Christian to widespread changes in thinking on what is or isn't acceptable on the sexual morality front.
In particular his comments on posture (sorry-thankyou-please-never) and dissection of why soft power is so attractive were really helpful. As a Christian I found it particularly useful to listen to the 'better story' that - when properly understood¹ - is incredibly liberating.

¹ meaning: when not being used for power games or ideological land-grab antics.
