Charles I belive the road block your hiting is.
The biblical definition of adultery verces the websters dictionary definition.
Since this is a christian web sight the definition of adultery is usually kept to the biblical definition.
In which sex of any kind thought or act outside of marriage or with someone other than your spouse is an act of adultery.
Websters dictinary's definition holds only sexual acts with someone other than your partner.
As for the question of masterbation there are two differant minds of thought mainly within the christian belifes.
There are those who think masterbation is a sin reguardless of thought, they belive the act itself is a sin.
Then there is the sect that belives its only a sin if your fantising about someone other than your life mate.
Either thought is valid for the beliver personaly I think masterbation is a normal sexual outlet and dont consider it to be wrong but then again i'm not a christian.
When speaking of homosexuals changeing thier ways perhaps the best view points can be found from Aineo who is christian yet has open eyes as far as the homosexual plight is conserned.
So his posts arnt the one sided view of someone who simply cant understand.
