These men are actually imagining they are as close as possible to being inside of a woman’s body. They lay in bed, self-pleasuring themselves, believing themselves to be stimulating the gorgeous woman of their fantasy. The Silence of the Lambs character is really an offshoot of this persona.
I haven’t seen any part of the video, but this is something I surmised, decades ago, from behaviors I’d seen and discussions I’d had, with similar guys who admitted they were attracted to women, while others went the next step and were fully gay, in the submissive role as the woman.
I’d guess you’d call the latter example as “fully down for the cause.”
"Autogynephilia is defined as a male's propensity to be sexually aroused by the thought of himself as a female. It is the paraphilia that is theorized to underlie transvestism and some forms of male-to-female (MtF) transsexualism."
It probably accounts for ALL post adolescent trans people...with the younger ones being simply brainwashed.
