The conversation is drifting. To me it seems obvious that the scriptures are not so much concerned about physical sex as prevention of the mixing of Jewish culture with vile, warlike idolatrous culture. Almost every time the word 'Fornication' appears in the KJV it is about this (probably every time by may require going beyond the surface reading). The only seeming exception is that men are told not to make their daughters into prostitutes, but I think that the law explains this is to prevent the dilution of Jewish culture with that of the nations around it. Its concerned that this will cause the land to be filled with whoredom, and whoredom is the dilution of Abraham's culture with worldly culture. In Christianity this becomes a prescription to be in the world but not of the world.
Ultimately whoredom and fornication are related to this and not so concerned with physical sex, although there are limitations related to sex both for Jews and for Christians. Christians are not under the law, so they are free. They can do what they think is right. Its an interesting idea.
Its a good idea not to get too stuck on particular laws or place too much importance upon them. Not having sex does not make you a good person. You can't make yourself awesome by not having sex anymore than you can do it by standing on one foot. Its simply not that important either in conscience or in the biblical canon. Lets not guilt trip people about things are not such a big deal. Lets instead emphasize what is important which is how they spend their time and resources. Maybe I don't have sex but I play video games all day. How is that better?
In fact Jewish men are allowed to fornicate under certain conditions, just like Judah is in the story; but they are required to be faithful to their children, to train them in the law. They have duties to their wives. They have to keep their wives happy and make them feel loved. Again, its not a huge deal if two people screw who can't have kids. In Christ, however, this is discouraged. If you're a Christian you should be focused on other things. Jesus would be I think.
Its therefore is a little strange to think of Jesus as a sexual person. He's not married. His mother symbolizes pure spirituality untainted by the world. Of course he's not screwing around with anybody, because he's a symbol of the undiluted essence of Torah.
The leak, here, in my explanation is that I don't know much about the culture that Jesus lives in. I can't say for sure if they really didn't allow male to male physical bonding. Its seems like they didn't, and it appears Paul the apostle to the gentiles believes that Christians should restrict themselves sexually to what is needed and not go beyond that. He believes marriage to be necessary for children, and he believes that sexal desire is an internal force to be conquered or compromised with. From this other more extreme church writers say some extreme things like "Sex is evil." Obviously not. Obviously its neither evil nor particularly good, which is why Jesus is probably not having sex. Its not particularly good.
