I believe sexuality can be suppressed, as people chose to be celibate but surely that would just mean a hetrosexual or a homosexual is celibate, not that their sexuality has changed?
This is what I was trying to say (much less eloquently
) above. We can choose what we do with our actions as a result of arousal, but arousal happens before we can even acknowledge it intellectually.
It makes no sense to me to argue that a gay person should stop being gay. If they are aroused by members of the same sex, that's what happens and it isn't a choice. As Bandit points out, science points to this being hard-wired.
However, it is worth noting that human sexuality is plastic. That is, cultures can (and have) made homosexuality the norm, and then the majority of people did have homosexual relationships. So it is not clearly a situation of social environment having nothing to do with sexuality. Clearly, it is both innate in
some individuals to be homosexual and possible to be culturally taught in
most individuals. Many surveys, starting with the Kiersey studies (did I get his name right?) in the 1950s, have found that it was very common for both men and women to have at least one homosexual experience in their lifetime. Most men and women were
mostly heterosexual but still occasionally attracted to members of the same sex in certain situations (that isn't the same thing as being bisexual, by the way, but does point toward the ambiguity of normal human sexuality).
And Bandit has a definite other point-- what about hermaphrodites and people whose hormone levels do not match their sex (i.e., biologically female but with high testosterone)? These folks are entirely ignored by Christianity and all either/or gender and sexuality systems. In reality, humans don't come in only two genders and they don't appear to come in only two sexualities either. How can we blame someone for something they did not choose? If a child is born a hermaphrodite, for example, or with secondary sexual characteristics (breasts, body fat distribution, hormones, etc.) that are ambiguous, how can we justifiably force them into categories where they clearly do not fit?
