let us first acknowledge that your request does not mention the name of Jesus Christ, Jesus, or Christ or an abbreviation such as IJN (In Jesus Name). We only have access to God only through the name of Jesus.
Acts 4:12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
In Jesus there is no distinction between male or female, Gentile or Jew, and this extends to marriage. If marriage is not honoring God, then biblically it is considered adultery or fornication.
We should be equally yoked in marriage as believers in the Lord Jesus Christ, but Arun does not imply if they believe in Jesus Christ. Marriage should be entered into with a fellow believer, and to address anything sexual you should be married to an unbeliever already as fornication is immoral.
Believers are not to engage in intimate physical activity with a boyfriend or girlfriend if this is implied.
Marriage is always for a man and a woman, not same sex, and marriage is implied by God to be 1 man and 1 woman for life.
Genesis 2:21 Yahweh God caused a deep sleep to fall on the man, and he slept; then he took one of his ribs, and closed up the flesh in its place. He made the rib, which Yahweh God had taken from the man, into a woman, and brought her to the man.
Genesis 2:24 Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh.
The same is true for the case of a woman. Please, Jesus willing, do not be unequally yoked.
If Arun should marry you and you are both Christians, then please do according to the will of God, and do not dishonor yourself.
The question implies God would disapprove and that you are not Christians, if not true, then please continue marriage according to the will of God and under the auspices of sexual morality and of a man and a woman. Lets us pray according to James 4:3.
Ye ask, and receive not, because ye ask amiss, that ye may consume it upon your lusts.
Here is a biblical prayer:
Almighty God, we come before You in the name of Jesus Christ, lifting up Zosulfean and Arun. We pray that Your will be done in their lives and that You guide them according to Your perfect plan. Lord Jesus we pray for godly spouse for each of them should it be Your will to not marry them and to intervene if it is not. If the path for marriage is not according to the plan you have laid out for each of them. If not then please have mercy on them according to your word and intervene to stop it if they will not listen. If they should marry we pray you will guide them into God honoring marriage together. If a biblical marriage should not occur we pray according to your will God. God, we ask that You help each of them be a believer and follower in the name Jesus Christ , and that Your Spirit may open their hearts and minds to Your truth. We pray that Your presence may envelop them in love, wisdom, and godly counsel. May they seek You earnestly praying in Jesus name.It is in Your name we pray amen.
