Yes there is hope, even without clinical re-orientation the statistics have shown that for the majority of male homosexuals it is a fleeting experience with most beginning young usually introduced to the lifestyle by older predatory males and leaving the lifestyle as they get older. Most homosexuals desire heterosexual normalcy and have in many cases tried to mimic normal heterosexual relationships with one partner assuming a dominant and the other a submissive partner role. You will often find a more masculine personality pairing with a more femine personality. This has been observed for some time and suggests that there is a some kind of underlying physchology that is distorting the natural attraction of men towards women.
I agree. Everyone is born heterosexual (aka as "normal") and there are a variety of factors that are known to cause homosexuality.
Later I'll post some links, don't have time at the moment.
