I completely stopped reading a famous author when I realized that her heroes constantly pushed and bullied their way into the heroine's body. *coughLoraLeighcough*
One of them refused to let her orgasm until she agreed to his cock in her ass (a pet peeve of mine, see Part Two of this series). One 'hero' repeatedly forced his sexual attentions on a heroine despite her concerns for maintaining her reputation/pregnancy/losing her autonomy. At no point did the hero address her emotional needs, preferring to shove his various body parts into her mouth and other locales of interest.
I left those books feeling violated, not aroused. Force isn't sexy.
When you are creating your erotic moment, remember that there is a huge
difference between a seduction and coercion. Seducing is an invitation to
pleasure and mutual joy. There is an element of play, of delight, of seeing who the other person is, and learning what works on this one in particular.
Coercion is about one person's "need" to get off. It also refuses to listen to the other's concerns and worries about the act of sex. If one person is worried about anything, then the partner had better address that.
Don't traumatize your readers or viewers. Invite them to play with you instead.
