Soon, when she could bear the scorching heat no longer, he would give her sweet release. Here we have the metaphor, 'pulling her into the sun' and the adjectives 'scorching and sweet'. A glorious sensation of wild heady freedom flowed in her veins. She abandoned herself to her own womanly power. The first two examples are from contemporary stories, the third, a historical, and the fourth comes from a futuristic.
Contemporary stories tend to employ action over metaphor, historicals, the reverse.
Probably because historicals have a more lyrical prose style overall. Speaking of historicals, I believe most Regencies stop at the bedroom door, although there are of course, exceptions. In a survey taken on Romance Central, the majority of participants said they prefer 'steamy' love scenes. Love scenes should overall be character-driven, and if attention is given to characterization in the scene, then that should make it as original as your characters. I attended a workshop given by author Glenda Saunders on love scenes a few years ago.
