Mankind did not internalize the law, consequently they went from bad to worse. From one evil to the next. God sent prophets and wise men to the people to encourage them to follow His word. They rejected the prophets. Finally God sent His Son.
In order to save the Jews, the Lord had to become what they had become: a prostitute.
God was deeply insulted by the Jews blatant prostitution with all the foreign gods of the surrounding nations. So, for Jesus crucifixion experience to be viewed as a violent sex act would be the Lord prostituting Himself to save His harlot wives: Israel and Judah.
The price for Christ's "services" is 30 pieces of silver - the going rate for a slave in those days. Judas sells Jesus to the Pharisees to use and abuse for their own "pleasure". He is then betrayed with the kiss of the "pimp" Judas. Christ's trial and torture become a kind of foreplay. Jesus is abused and killed to "satisfy" (pay) the "pleasures" (sins) of the Pharisees (His people). God proves how "impotent" the Pharisees really are, who when unable to perform the act, actually turn to the repulsive - unclean Romans to kill Jesus. Jesus "passion" on the cross is a kind of coitus. Concluded by His orgasmic death in which He pours out His Spirit.
The sexual connotations of this cannot be avoided. The "Y" and the cross can be seen as symbolic of God's penis penetrating the womb of creation (Eve) as the cross is slammed violently into the earth.
This is why sex is so attractive. It is the fleshly mirror of intimacy and love built into God's name - Yihvah. Sex is only right in the context of heterosexual marriage. Because it mirrors God the creator - its purpose is to create life. This also makes sex a very holy thing.
Praise Lord God!
