According to Scripture, the purpose of a male/female marriage is to be fruitful and multiply. Obviously, the male has a part that fits the females part by God's design. Now, does every time the act of sex produce a child, no, but I guess where the thought of practice makes perfect comes into mind. But one thing is for certain, oral sex and anal sex cannot ever produce children. That leads to the thought process that those sexual acts are not what God had intended (and why Homosexuality is a sin because any acts by same sex partners can never produce children).
As far as masturbation is concerned, will it be fruitful and multiply?
If we stay within the confines of what God instructed Adam and Eve, we can easily deduct what God's intent was compared to what our lusts contradicts.
The Bible does not discuss masturbation explicitly or mention whether or not it is a sin. So any judgement of whether or not masturbation is a sin or not is purely speculation and since there are no scriptures that specifically say the masturbation is a sin then it is not a sin.
If it is not written in the Bible it is not.
We need to remember that men produce sperm 24/7,s and that is the way God made men. So the body needs to release at some point which leads to what is called "wet dreams" which cause a release during the night which a natural function of the body that God made. It also leads to the man's desire to get release from the feeling that comes with the fullness feeling. That to is how God made us.
So in Leviticus there is instruction as to what God required of the men who had a night time release.
Lev 15:16 And if any man's seed of copulation go out from him, then he shall wash all his flesh in water, and be unclean until the even.
Lev 15:17 And every garment, and every skin, whereon is the seed of copulation, shall be washed with water, and be unclean until the even.
Deu 23:10 If there be among you any man, that is not clean by reason of uncleanness that chanceth him by night, then shall he go abroad out of the camp, he shall not come within the camp:
Deu 23:11 But it shall be, when evening cometh on, he shall wash himself with water: and when the sun is down, he shall come into the camp again.
These verses are not specific as to whether or not they are talking about masturbation or a "wet dream". But according to these verses if a man has a release during the night it is considered to be unclean and there is no punishment associated with the act of the release but cleansing one's self is required so no it is not considered a sin according to these verses.
However if a man fails to cleanse himself it is considered a sin.
Lev 22:4 What man soever of the seed of Aaron is a leper, or hath a running issue; he shall not eat of the holy things, until he be clean. And whoso toucheth any thing that is unclean by the dead, or a man whose seed goeth from him;
Lev 22:9 They shall therefore keep mine ordinance, lest they bear sin for it, and die therefore, if they profane it: I the LORD do sanctify them.
However what men are thinking about during the release could be a sin. In the Old Testament it was not a sin to lust in the mind bt in the New Testament it is a sin to lust just by thinking about committing a sin.
Mat 5:27 Ye have heard that it was said by them of old time, Thou shalt not commit adultery:
Mat 5:28 But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
This is an example of how Christ "fulfilled" the law making it a sin to even be thinking in a lustful way about a woman.
Oral sex is also permissible and not a sin in a marriage.
The Bible makes no clear mention of oral sex at all. Therefore, it is difficult to produce an official biblical position. Nevertheless, based on the information that follows, oral sex is not sinful and that it is permissible only within the bonds of marriage between a husband and wife.
The book Song of Solomon is a love poem between a husband and wife. This book is seen in two senses: physical love and a description of God's love for His church. Either way, the book definitely encourages a husband and wife to enjoy the sexual pleasures of one another. It is in this beautiful book that two scriptures appear which may shed light on the issue of oral sex. Let's take a look.
Song 2:3, "Like an apple tree among the trees of the forest, so is my beloved among the young men. In his shade I took great delight and sat down, and his fruit was sweet to my taste."
Song 4:16, "Awake, O north wind, and come, wind of the south; make my garden breathe out fragrance. Let its spices be wafted abroad. May my beloved come into his garden and eat its choice fruits!"
Notice in
Song 2:3 that it says, " . . . and his fruit was sweet to my taste." Obviously, this involves very intimate experience. Tasting one another can have a wide variety of applications. It appears that this is a veiled way of alluding to oral sex. Furthermore, if we look at
Song 7:8 we read, "I said, I will climb the palm tree. I will take hold of its fruit stalks. Oh, may your breasts be like clusters of the vine." Apparently, fondling of the breasts is meant here. If such enjoyment of the body is intended and since tasting (which involves the mouth) is part of that expression, it would seem safe to say that oral sex is permissible.
What does it mean to eat the choice fruits of his garden in 4:16? She is saying that she is "his garden" and that she desires that he eat of her fruit.
The poetic use of metaphors in describing the physical relationship is sometimes hard to fully apprehend, but it seems obvious from the context that intimate sexual union is implied.
"The beloved's request that the winds blow on her garden, that is, herself was a delicate, poetically beautiful invitation to her lover to fully possess her (come into her). She wished to be his with her charms as available as fruit on a tree."

Therefore, oral sex is permissible between a husband and wife.
Here is all the Scriptural proof you need to show that neither masturbation or oral sex in a marraige is not a sin and anybody that advises you any differently is giving you a non scriptural unprovable doctrinal belief and is nothing more than an assumption.
