Zunächst möchte ich mich von der (meist christlichen) Anschauung, Homosexualität könnte man ändern (oder „heilen“) distanzieren! Die sexuelle Orientierung ist angeboren.
Schwere Traumata (hier Vergewaltigung) haben großen Einfluss auf die Sexualität. Da wird ja jeder zustimmen. Neben den "üblichen" Effekten, passiert es anscheinend auch, dass sich manche heterosexuelle Opfer von Vergewaltigung dem gleichen Geschlecht zuwenden.
Sicherlich ist das Vorhandensein homosexueller Kontakte nach einer Vergewaltigung nicht mit der natürlichen Homosexualität gleichzusetzen (was in Walker et al. 2005 beschrieben wird).
Ich denke, wenn sich eine Frau nach einer Vergwaltigung eine andere Frau als Lebenspartner aussucht, spielt hier auch das allgemeine Misstrauen (und vllt. sogar Ekel) gegenüber Männern eine große Rolle, sowie ein Haufen, anderer persönlicher Gründe.
Zudem wird über eine Verwirrung/Krise bezüglich der sexuellen Orientierung gesprochen (Davies 2002). Dies kann natürlich verschiedenste Ausprägungen haben und muss nicht zwingend auf das Suchen nach homosexuellen Kontakten hinauslaufen.

"McMullen (1990) suggested that it is not unusual for heterosexual victims to seek out homosexual contact after rape or, in contrast, manifest irrational loathing or hatred of all gay men (because they assumed the perpetrator(s) to be homosexual.) Walker (1993) reported tha 80 % of the heterosexual victims in her study reported experiencing long-term crises over their sexual orientation"
Hier noch eine Erklärung (Walker et al. 2005) für das Suchen nach homosexuelle Kontakten nach einer Vergewaltigung.
“Several men reported changes in their sexual behavior after the assault. Some became promiscuous, while others refused to have sexual relations with either men or women for a considerable time after the assault. Sexual problems included erectile failure and lack of libido. One described his sexual experience after his assault as one of promiscuity and sexual compulsion:
Before the assault I was straight; however, since the assault I have begun to engage in voluntary homosexual activity. This causes me a great deal of distress as I feel I am not really homosexual but I cannot stop myself having sex with men. I feel as if having sex with men I am punishing myself for letting the assault happen in the first place.Unlike this man, since his assault the following had not engaged in sexual relations with anyone:
Since the assault I believe I no longer have a sexual
orientation. I no longer want a sexual relationship with a
man or a woman. I feel sex is a horrible act and just an
excuse for an individual to experience self-satisfaction.”

"[...] it is a myth that all men who are raped are gay. Because of the operation of this myth, many heterosexual victims question, or become confused about their sexual orientation post-rape. Additionally, after rape, both gay and heterosexual victims may experience severe homophobic reactions towards other men. In extreme cases, fear of being assaulted again may reach levels of paranoia and in extreme cases this can develop into chronic disability,
such as agoraphobia (Anderson, 1982). Long-term problems of male victims also include sexual dysfunction, relationship difficulties, and, in the heterosexual victim, a loss of gender identity and, as previously stated, confusion of sexual orientation (Anderson, 1982)."

;) Aber die Top-Antwort beschreibt es ziemlich gut, find ich.

What happens during such trauma is it's not their sexual orientation that changes it's their perception of sex in general. It all depends on the person, their mentality and how the aftermath was handled. Some people withdrawal from sex, others become aggressive towards their sex partners. There really isn't any percentages as each case is NOT the same as the other.
In terms of rape and sexual orientation, studies have shown straight victims finding solace in the same sex if raped by the opposite sex but not sexually, more that they have trust in the same sex and regard all of the opposite sex as an abuser. Others of the same category with proper treatment can have perfectly normal sex lives and healthy relationships...It all really depends on the individual.”
