Nothing more than speculation, but I am inclined to believe that the accused would likely be very drawn to fantasies based around BDSM. However, I see him as having a highly emotionally avoidant attachment style, with a significant hostility towards women, probably as a result of feeling very remote from females as he was going through his adolescent development and becoming sexualised, feeling like he was entirely unable to relate to girls despite being highly attracted to them, and feeling highly inadequate as a result. I think that peeping and stealing clothing off lines would have been a means to feel a sense of sexual closeness to women, to whom he felt quite alienated. I suspect the accused would likely have also had a very precious collection of *advertiser censored* at the time which helped him feel sexually satisfied, but also shaped his internalised ideas and expectations around sex (and the dominant role of men in sex), as well as playing a strong role in the neural wiring of his brain relating to sexual pleasure and the need for increasingly strong sexual stimuli to create satisfaction. I think it's likely he would have 'graduated' towards BDSM *advertiser censored* due to the increased 'strength' of sexual content and stimulation, but also because of the theme of power and control as a way to sexually express his hatred towards women for his feelings of inadequacy and rejection. But I suspect that given his emotionally avoidant constitution and highly private nature, that it would likely have remained a strongly private pursuit, and while he might have deeply wanted to 'experiment' in these areas, that he was unable to manage this and that his desires lay deeply embedded in him without any opportunity to externalise them in a context other than his sexual violence. I suspect that even if at some point his own consenting relationships might have had the opportunity to explore these themes, that he would have felt exposed, shameful and inadequate, and much more comfortable leaving them to be his own private delights. I also expect that it would not be the least bit surprising to discover the accused to have been domestically abusive, i.e. controlling and domineering, overly black and white and punitive, emotionally cold and distant, and at times verbally, emotionally, psychologically, and even physically and sexually abusive, all the while appearing to be an upstanding family man to even those closest around him. I also expect him to have continued his engagement with extreme *advertiser censored* to satisfy his sexual fantasies.
I will say that although I believe his behaviour has been an expression of his private inner world, I am troubled by the earlier incident noted in Debi Marshall's book involving the attempted abduction of a women in Claremont from a taxi, whereby a man crouching in the back tried to pull her in, and she was able to escape with a broken ankle or similar. Clearly, this was the reason for the suspicion of Peter Weygers and Steven Ross, but it strikes me as such a brazen and sinister attempt at abduction with highly nefarious motives, that I have found myself questioning if it might be possible that some of the attacks could have involved an accomplice, whom shared a history of having been sexualised in an aberrant way.
