In short, much of what I read in your arguments seems to be based on a need for physical purity. While that is important, and marriage is definitely a safeguard against it, marriage doesn't solve it.
You have the issue backwards. The question isn't 'how so I solve the problem of physical purity' but 'what does God command?' What does God command in the area of, as you put it, physical purity?
I Cor 7 1-2 Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman. Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.
I Cor 7:3-5 Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband. The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife. Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.
I Cor 7:8-9 I say therefore to the unmarried and widows, it is good for them if they abide even as I. But if they cannot contain, let them marry: for it is better to marry than to burn.
Prov 5:1-20 My son, attend unto my wisdom, and bow thine ear to my understanding:That thou mayest regard discretion, and that thy lips may keep knowledge.For the lips of a strange woman drop as an honeycomb, and her mouth is smoother than oil:
But her end is bitter as wormwood, sharp as a two-edged sword.Her feet go down to death; her steps take hold on hell.Lest thou shouldest ponder the path of life, her ways are moveable, that thou canst not know them.
Hear me now therefore, O ye children, and depart not from the words of my mouth. Remove thy way far from her, and come not nigh the door of her house:
Lest thou give thine honour unto others, and thy years unto the cruel:
Lest strangers be filled with thy wealth; and thy labours be in the house of a stranger; And thou mourn at the last, when thy flesh and thy body are consumed,And say, How have I hated instruction, and my heart despised reproof; And have not obeyed the voice of my teachers, nor inclined mine ear to them that instructed me! I was almost in all evil in the midst of the congregation and assembly.
Drink waters out of thine own cistern, and running waters out of thine own well. Let thy fountains be dispersed abroad, and rivers of waters in the streets. Let them be only thine own, and not strangers' with thee.
Let thy fountain be blessed: and rejoice with the wife of thy youth. Let her be as the loving hind and pleasant roe; let her breasts satisfy thee at all times; and be thou ravished always with her love.
And why wilt thou, my son, be ravished with a strange woman, and embrace the bosom of a stranger?
Those are God's words, by the way, not mine.
