I would like to diverge from the previous post. I think that the social stigma that is present would complicate the issue of men being raped. I think that the perception of rape victims is that women are the primary victims. While this is true, I think that men do feel a bit of a shame factor in confessing their assaults. This silence, as in women, empowers the aggressors and helps to take away the dignity of the victims. In no way would I decrease the impact of the rape of women, but rather would point out that there is a level of stigma attached to men speaking out about their rapes or assaults.
As it is, the male role in the sex act has an inherent element of aggressiveness which can easily turn to violence. If the genders were 'switched' so the "female" became the one who did the penetrating, I would think that the "male's" psychology with respect to rape would be alot like that of real females.
It is also possible for a female to rape a male, using some form of intimidation. In that case also I would think the male's reaction would be alot like a woman's with the added pain that it is socially and psychologically more difficult for a male to admit to being victimized by a woman.
Pleas remember rape is something forced on the victim, against the wishes of victim. I am unable to see a situation where an occurrences like this can be anything but traumatising for the victim, male or female. Perpetrators of rape are not seeking only sexual pleasure, they are also derive psychological pleasure from the feeling of being able to forcibly dominate and humiliate others.
Rape is just one of the ways of physically dominating and humiliating a helpless victim. Another such common practice, at least in India, is that of ragging new students in institutes of higher education. It is not uncommon to read of victims of such treatment committing suicide.
It is a hypothetical question in which the physical realities of what is possible and what is not possible are irrelevant. What I would like to consider is the psychological effects if somehow such a thing was possible.
In that case I see no reason why a rape will be as traumatising to men as to women. Men may show or respond to their emotion differently but the basic effect will be same. Further, I believe a sense of being humiliated would be the main emotion for men, as perhaps is the main emotion experienced by women suffering such a fate.
Only difference I see is that men need not worry about conceiving.
I am not sure if they would be similar unless there was a circumstance of having an environment factor play into considerations, such as at the office, or in the workplace. Or, if there was some kind of team relationship, where that person must be seen again.
If the personw as enevr to be seen again, the man might have the same reactions a s a woman, but not to the degree psychologically.
