Re: foggy
It is "POSSIBLE" that it went further, but unlikely (not 'probable'). It's the classic psychological tactic of evil.
The guys who are CLAIMING that it went further 'WANTED' you to hear that it did go further...for a very specific reason...
...they want you to think less of yourself....they want to DEMORALIZE/dehumanize you so you will be more easily manipulated to cooperate in their evil scheme,...they are trying to psychologically condition you so that you give up being the moral person you are (DE-moralize).
A similar psychological tactic is used on prisoners of war (P.O.W.s) to break their spirit (demoralize them) so that they have no more will of their own and are easier to handle.
The "guys" (they are not 'real MEN', they are and always will be 'little boys'....slugs, dogs), but since they were all complicit and let this happen, they want you to think that it was all consentual (because they don't want you to report it to the police), so they actually have a NEED to break your spirit.
Since you don't have a clear memory about the incident, there probably isn't much you can accomplish by going to the police without retaliation from "the guys".
Without a doctor's examination, you probably won't be able to know for sure if you got an STD or are pregnant until it's too late.
Be careful, this is how people cause evil to happen to a person...they first condition the person ("demoralize" them to accept abuse) in order to gain "cooperation".
