A Knight in Broken Armor (The Knights of Stonebridge #2)
Bambi Lynn

But Kier shows no interest in her attempts to seduce him. Ivy has grown up with this troupe of prostitutes, so she is not ignorant of relations between men and women. Imagine her disappointment and frustration when she finds it impossible to seduce the man she has chosen to be her first.
Kier, reluctant to explain his impotence, tries to discourage Ivy. But he underestimates her determination. Without benefit of a modern-day sex therapist, it is up to these medieval lovers to find a cure. Ivy’s antics while trying to learn all she can from her friends will have readers laughing out loud before racing for a cold shower.
