F U in Your Mind Hole

As I continue on my paranormal romance journey - at times carefully navigating the alpha male/forced sexual encounter line - I've discovered the appeal of a certain trope of paranormal loving. Often the alpha male is so big (literally his giant penis is so big) or so scary or so strong that the heroine is afraid or timid and in order to woo her he must first come to her in her dreams, a.k.a f her in her mind hole. These dream encounters are so lovely and sensual that the heroine no longer fears his giant man (cock) and soon welcomes him in to her bed.

Oh baby you're so dreamy please do me in my dreams ...

Oh no, I could never say yes to you, unless you do me in my dreams ....

These fantasies skirt the line of rape (he's immortal and therefore willfully controlling her dream), but they also open the door for the heroine to release her inhibitions and give in to her desires - they find a way to appeal to the desire for capture, rescue, protection fantasies while simultaneously appealing to the desire for strong, sexy heroines. Is this trope troubling? Perhaps, depending on how it's written - but it can also be incredibly hot.
