I've reviewed, and now I'll try to better address just exactly what you are talking about only --
I've spent an hour or 2 over the years looking at translations of the original Hebrew in the Old Testament on this, such as in Leviticus -- "You shall not lie with a male as with a woman; it is an abomination." in chapter 18. Which seems to be specifically intercourse sodomy -- just 1 thing.
And others have spent time, such as the translators for instance of the ESV, to give a good example, or the NIV, to get the translation accurate.
And their translations in the Old Testament (O.T.) and New, both, make it seem there is just this 1 precise, specific act only (only just 1) that is forbidden among consensual sex between adults that are in a monogamous faithful relationship.... (and the 1 act is forbidden for
all couples, of every sort, including man/women, traditional married, etc.) This 1 act, and not any others of the various non-coerced acts.
Which leaves
everything else between consenting adults (who are faithful to each other) which isn't that particular 1 thing.
Since we are instructed in the O.T.
not to add extra stuff into the words than only what they say..... then we shouldn't add extra meanings! (anyone wanting to see this instruction just ask me)
If you got a book of sexual techniques, this 1 thing would be like only...1% of the techniques.
That leaves the other 99% still left one could do.
You shouldn't trust those prejudiced political positions you have heard and that many loud voices claim is "Christian" -- they didn't even read carefully! (or they just trusted some preacher that didn't read carefully). (also, for that matter, ask Christians at a church that isn't so political as to endorse Trump for instance, but are more oriented instead to Christ, and if you ask 20 people, you might get 20 distinct opinions, but probably will hear mine among them)
When you have a non-politicized translation that is accurate -- good ones are the ESV and NIV for instance -- then you have a lot of freedom in a monogamous relationship that is faithful.
So, we can turn, again, to the key, crucial thing that helps us understand --
The rule for all actions, of every kind, every situation:
Matthew 7:12 In everything, then, do to others as you would have them do to you. For this is the essence of the Law and the Prophets.
So, you see why it mattered my last post previously not to accept just whatever the political-power-seeking Christians that will insist is Christian, when it's often just their prejudice. They have created a powerful false impression.
