let me make a deal with you i will answer the first quote, which is "your wives are a tilth for you;so go to your tilth when or how you will" Qur'an 2.223. If you found the answer decent and convincing i will answer the rest of them. This quote is authentic and right, there is a reason of the revelation of this verse it is the following "(Your women are a tilth for you…) [2:223]. Abu Bakr Ahmad ibn al-Hasan al-Qadi informed us> Hajib ibn Ahmad> 'Abd al-Rahim ibn Munib> Sufyan ibn 'Uyaynah> Ibn al-Munkadir that he heard Jabir ibn 'Abd Allah say: “The Jews used to say that whoever penetrates the vagina of his wife from a back position, the child born as a result of this intercourse will be cross-eyed. To deny this, Allah, exalted is He, revealed (Your women are a tilth for you (to cultivate) so go to your tilth as ye will)”, meaning: from in front of her and from behind her as long as the penetration is done in her sexual organ”.

The second thing that the Quran says (your women) to make clear that the only being that the man can have sexual intercourse is woman and vice versa, to abolish the idea of homosexuality and so on. another thing the Quran is so accurate it its words why Allah(God) said (your women) when it could be (the uterus of your women), lately scientists discovered that seminal proteins can directly affect behaviour because they enter the circulatory system, travelling throughout the body to the brain.

so the affect is in the whole body not in a special organ.
the last thing why the word (tilth), because that is the most accurate word could be used in this position and it is refaring to the process of Implantation.

and Allah(God) said for you meaning that the husband is the only one can enjoying his wife and the wife the same, and it is forbidden to do that with foreigners.
Finally, God explained to us in the Quran the fact of the relationship between man and his wife when he said "And of His signs is that He created for you from yourselves mates that you may find tranquillity in them; and He placed between you affection and mercy. Indeed in that are signs for a people who give thought"(Q 30:21)
