This twisted approach to sexuality and the oppression of female sexuality in particular within Evangelical Christianity is very depressing as you well know.

I have observed that women brought up 'conservatively' can be fairly easy to have sex with if given license. I have found that they won't seek it out but the license allows them to engage and enjoy. I have found two effective forms of this license. One is to point out that there is no such thing as original sin and therefore sex is not a sin. The other to deprogram more extreme cases of brainwashing is to point out that if you truly believe that you have accepted Christ as your personal savior that means that you are living in a state of grace and therefore sex is no longer sinful. Either approach can assist in liberating a woman from the pernicious doctrines promulgated by these churches.
