Quran 24:32 Marry those among you who are single, or the virtuous ones among yourselves, male or female: if they are in poverty, Allah will give them means out of His grace: for Allah encompasseth all, and he knoweth all things.
Quran 24:33 But let them who find not marriage abstain [from sexual relations] until Allah enriches them from His bounty.
It seems to me that marriage is something that you should be actively looking for. If you cannot find it, you should not have sex and wait until you find it.
I get the impression that you should desire marriage and should try to get married. Is it thus sinful if I desire to be single forever and not look for marriage? The Quran seems to say that I should be looking for marriage. Am I obligated to marry if I have the ability to marry, but choose not to?
To me marriage is not going to make my life any better. I find peace in loneliness and I do not plan on having children. My sexual desire is at a minimum. I don't find many women attractive and I do want anything to do with anyone. Is this a sinful lifestyle as per the Quran?
Please ignore any personal bias. Objectively, from the Quran--Am I supposed to actively look for marriage? Personally, I do not connect with people and cannot form emotional connections with people. But I can pretend for Allah.
I find no issue with getting married just for Allah. But I would be doing it just because I was told to--not because I want to and not because I would love my spouse. Quite the contrary, I don't think I would love her--she would just be something I use so that I fulfill my obligations towards Allah. It would be like prayer. You do it just because Allah commanded it and you want to get closer to Allah.
