I haven't recovered my lost post and any rewrite is beyond me at the moment, but I hope the following will enable you to see what manner of man you had dealings with on Tuesday night.
He is not the type that prowls the streets looking for lone women to sexually assault. He doesn't watch to establish whether a property is occupied by a lone woman before breaking in to sexually assault her.
As he's not driven by compulsion to commit sexual offences on a regular/ predictable cycle, he chooses his victims as and when opportunity arises.
He is arrogant. He doesn't believe he will be caught but he targets women who are of a similar age to him partly so that he cannot be accused of taking advantage of a significantly younger women.
In additon, this enables him to take advantage of the speedy establishment of common ground which can occur when making the acquaintance of someone from a same/similar age group for the first time.
He selects his victims on the probability that he will be able to overpower them. They will be smaller in height than he is and/or of slim build.
He is confident in his masculinity - he works out or keeps himself fit/in shape by running, rowing, swimming etc.
Unlike another category of 'date rapists', he will not seek to get his victim drunk/drugged to the point of being semi-conscious/out of it, but he will use alcohol/drugs to give himself 'dutch courage'.
When committing sexual offences he is aggressive and will use force as he sees fit to subdue his victim. He may say abusive or humiliating words/phrases or use commands. He looks solely to his own pleasure - there is no foreplay.
He uses the power that he is able to exert over his victim to prove his virility.
Men who fall within this category of rapists do not necessarily lack empathy towards others but they are able to suppress empathy towards their victims to the extent that they are not concerned about them either before, during, or after the act.
These men are cunning and the man who raped you is more practised than most as his employment has given him more access than most to women who, in common with yourself, did not believe that a man who saves lives for a living could harm them... until they discovered otherwise.
Everything you've said about your experience indicates that he's raped before, Crispy, and he's going to rape again...and again, until old age or the law stops him.
