Are you saying that because someone is a virgin, they cannot have ever been sexually abused/assaulted?
No, I'm not. There is no information by the OP about prior sexual abuse to warrant a reaction based on violent sexual assault.
Are you saying that unless penetrative sex (with a penis) takes place, there can be no sexual abuse/assault?
No, I'm not. Sexual assault, in agreement with you here, in USA, Canada, UK and Australia, are all near identical from a legal perspective. All forms of forced sexual content fall under the one umbrella, sexual assault. They add additional identifiers typically, i.e. penetrative sex, so forth.
It is actually very common for people not to say stop or say no or fight back during sexual assaults. It is very common for people to totally freeze. And I would argue that if someone is in a totally frozen, shut down state, they are not actively participating, so actually no mind-reading is required.
It is also common for this reaction without being sexually assaulted, especially for first-time consensual sexual events. The OP has not claimed shutting down, they stated they panicked, it then passed, they then faked an orgasm. The OP is not stating what you are.
My point is very simple: the OP is using the word assault in conjunction with a sexual encounter. That means sexual assault, aka rape. Same definitions legally.
Nothing being stated says rape / sexual assault.
@Friday summated the wording accurately.
The male is being perpetrated as a sexual offender, and in this instance, it is totally wrong. Based on what the OP has stated, are you saying
@barefoot that this male should be charged for sexual assault? Because the OP panicked, at no stage did she "shut down" as you used, but she felt panicked (her words), then calmed, made an active decision to not say STOP or NO to the guy, and instead faked an orgasm to bring the event to cessation. He thought everything was mutual, obviously, and was then baffled why nothing further took place. He did not force himself at any time upon her. She did not say STOP or NO at any time.
She is embarrassed, sure. She feels guilty for not acting differently / for having oral sex. She feels distressed for him being a douche after the fact and bad mouthing her.
Is this man a sexual predator? A rapist? If you answer yes to that, back it up based on OP statements and not your own interpretations of freeze or such, which the OP has not used. Panic was used, a panic attack, then calm, thought, not wanting to upset him, at no stage saying no or stop, but calmly allowing the encounter to continue with control, all the time letting this guy believe everything is ok.
Is my view disturbing? I don't believe so. I call a spade a spade when it comes to information about sexual assault. Add more info by the OP that eludes to assault, I will absolutely change my mind. Until then... assault should not be used, as this was not sexual assault.
The OP is more concerned about their friend being friends with the boy, than it seems the event itself. WTF?
