Depends. How long has he been clean of it. Has he sought and received counseling to cure the underlying trauma that causes this particular mental illness. How strong of a Christian is he. Is he a virgin. Lots of questions would need to be answered. Of course ANY guy who wanted to court my daughter would be run through the wringer. Polygraphs and all.
me->There is no genetic cause of homosexual behavior.
you->What you are really arguing for is that there is no genetic cause for any sexual behavior.
No. All normal heterosexual behavior is genetically driven (look at the biology, man fits woman). Abnormal behaviors are driven by various mental illnesses caused by various things, none of which are genetic
Why does one person experience a certain temptation and another person will not?
Male homosexuality is caused by one or more of the three following conditions. 1. An absent or insufficient relationship with ones father. 2. Being molested or otherwise abused. 3 Relentless teasing by one's peer group during the formative years.
Those who've experienced the above will experience some level of trouble with this UNLESS or until these underlying causes are dealt with. Those who claim to have never experienced one of these causes yet still struggle with homosexual desires are lying to themselves and to us.
