A-spot

I searched for information about the A-spot and I found this:

When highly aroused, the uterus lifts up and exposes a tiny space behind the cervix that a partner can stimulate for deeper, more intense explosive orgasms. The spot is usually hidden and is full of pleasurable nerve endings. To help your partner go the distance, try a position that maximizes penetration, like rear vaginal entry or missionary style with your legs up by your head.
An A-spot orgasm comes from the area deep and on the upper wall of the vagina. A cul de sac orgasm comes from the bottom wall of the vagina, underneath the cervix. Women often report that the A-spot orgasm is better than the G-spot orgasm. I believe all women who experience the cul de sac orgasm or the cervix orgasm declare either one to be beyond compare. Barbara Keesling said concerning the cul de sac O, it’s great for when you have a man without stupendous endurance, because it’s the quickest vaginal O. But the trick is that cervix must be up, so you must have tremendous arousal before penetration.https://www.quora.com/What-is-the-difference-between-a-cul-de-sac-orgasm-and-an-A-spot-orgasm-How-do-they-feel-How-long-does-it-take-to-stimulate-properly

Though the A-spot usually located 5 to 6 inches inside, shorter penises can reach it too, if the receiving partner’s knees are pulled up to shorten the vagina. As with G-spot stimulation, the penis should be aimed toward the front wall, but inserted extra deep to access the A-spot.

Sex educator and pleasure coach Glamazon Tyomi discovered her A-spot while with a partner. “I began to realize how moist I would become in certain positions when my partner was deep. The increase in wetness would also come with a warm, calming, euphoric feeling across my body, and I noticed that it would happen with deep penetration near my cervix... I knew this wasn't something that was commonly experienced or discussed, so I began to do research.

”Positions that shorten the vagina (legs brought closer to the abdomen or chest) can help penetrating partners find the spot more easily,” Tyomi suggests. “I also recommend 'planking' position as a way to locate the spot easily.”

“Fingers can provide the deliberate pressure and steady rhythm that my A-spot likes... I also find it ridiculously hot on a psychological level when a partner fingerbangs me to orgasm this way. It displays a mastery of my body that I find incredibly hot. Toys with curved ends, like the Abby G, are really good at nestling in there and getting at the A-spot, too.

”Our partners love the feeling of our vaginas becoming wetter and tighter, quivering with pleasure… the slippery texture of the A-spot feels good to rub up against.” “The penetrating partner may have to shift a little to the right or to the left, or even shift their partner's legs to one side or the other to access the spot more easily. Patience is key.”

If you continue to hit the A-spot just right, you’ll get an intense orgasm that lasts about 20 seconds longer than any other one. Cadell says that hitting the A-spot should feel similar to the G-spot, without the need-to-pee sensation.

Bahaullah and Abdul Baha on sex, marriage and divorce.

"He is My true follower who, if he come to a valley of pure gold, will pass straight through it aloof as a cloud, and will neither turn back, nor pause. Such a man is, assuredly, of Me. From his garment the Concourse on high can inhale the fragrance of sanctity.... And if he met the fairest and most comely of women, he would not feel his heart seduced by the least shadow of desire for her beauty. Such an one, indeed, is the creation of spotless chastity"(Baha'u'llah, Gleanings from the Writings of Baha'u'llah, p. 118)

"Say: O concourse of monks! Enter ye into wedlock, that after you another may arise in your stead. We, verily, have forbidden you lechery, and not that which is conducive to fidelity."
(Baha'u'llah, Epistle to the Son of the Wolf, p. 49)

"Ye are forbidden to commit adultery, sodomy and lechery. Avoid them, O concourse of the faithful. By the righteousness of God! Ye have been called into being to purge the world from the defilement of evil passions. This is what the Lord of all mankind hath enjoined upon you, could ye but perceive it. He who relateth himself to the All-Merciful and committeth satanic deeds, verily he is not of Me. Unto this beareth witness every atom, pebble, tree and fruit, and beyond them this ever-proclaiming, truthful and trustworthy Tongue."

“Ye are forbidden to commit adultery, sodomy and lechery. Avoid them, O concourse of the faithful,” Bahá’u’lláh states.

"It is forbidden you to wed your fathers' wives. We shrink, for very shame, from treating of the subject of boys. Fear ye the Merciful, O peoples of the world! Commit not that which is forbidden you in Our Holy Tablet, and be not of those who rove distractedly in the wilderness of their desires." (Baha'u'llah, The Kitab-i-Aqdas, p. 58)

And when He desired to manifest grace and beneficence to men, and to set the world in order, He revealed observances and created laws; among them He established the law of marriage, made it as a fortress for well-being and salvation, and enjoined it upon us in that which was sent down out of the heaven of sanctity in His Most Holy Book.

God hath prescribed matrimony unto you...Enter into wedlock, O people, that ye may bring forth one who will make mention of Me amid My servants. This is My bidding unto you; hold fast to it as an assistance to yourselves.

Abdu’l-Bahá has stated the following in this regard:

Bahá’í marriage is the commitment of the two parties one to the other, and their mutual attachment of mind and heart. Each must, however, exercise the utmost care to become thoroughly acquainted with the character of the other, that the binding covenant between them may be a tie that will endure forever. Their purpose must be this: to become loving companions and comrades and at one with each other for time and eternity…
The true marriage of Bahá’ís is this, that husband and wife should be united both physically and spiritually, that they may ever improve the spiritual life of each other, and may enjoy everlasting unity throughout all the worlds of God. This is Bahá’í marriage.
In another Tablet, He has written:

O ye two believers in God! The Lord, peerless is He, hath made woman and man to abide with each other in the closest companionship, and to be even as a single soul. They are two helpmates, two intimate friends, who should be concerned about the welfare of each other.
If they live thus, they will pass through this world with perfect contentment, bliss, and peace of heart, and become the object of divine grace and favor in the Kingdom of heaven. But if they do other than this, they will live out their lives in great bitterness, longing at every moment for death, and will be shamefaced in the heavenly realm. Strive, then, to abide, heart and soul, with each other as two doves in the nest, for this is to be blessed in both worlds.

As for the question regarding marriage under the Law of God: First thou must choose one who is pleasing to thee, and then the matter is subject to the consent of father and mother. Before thou make thy choice, they have no right to interfere.

Divorce is, according to the Aqdas, permissible. But it is discouraged. Both the husband and wife have equal right to ask for divorce, and whenever either of them feels it absolutely essential to do so. Divorce becomes valid even if one of the parties refuses to accept it, and after one year of separation, during which period the husband is under the obligation of providing for his wife and children.
