I am extremely practical when it comes to these matters. A good companion would be my goal. For some, sexual interaction isn't their hot button. they'd rather have the peace and safety and companionship of a solid relationship as a trade off from the ups and downs of that super sexy relationship. However, you sound very much like you already know this isn't the person for you. And just because someone is available and offering, doesn't mean you have to accept. I understand the urge to make it easy. And hey, if you so desire, it could work out knowing that you are compromising some things to have a life with a man and a family. My wildly romantic relationships ended and those men would not have been good husbands. Period. But then I found one that I enjoy, relate to and am also attracted to but it is peaceful. Been married over 20 years now. Practical worked for me. :>))
Remember that being in a rotten marriage is horrible. So, while you may not have bells and whistles, you want to be happy over all. So, pick wisely.
You happen to live in a country where women can get pregnant a little later in life due to the availability of IVF, so don't panic and make a bad life choice. One thing you can do right away is find a reputable clinic and get your eggs frozen. That will give you a bit of a breather timewise to find someone to marry who you actually can imagine having sex with.
The problem with marrying a man with whom you simply can't picture having sex is that many men, especially in India but really all over the world, see sex as a right (to the point unfortunately of violence in some of the terrible cases in India that have been in the news). It's a cultural expectation even with the nicest guys that if they are married, they get sex pretty much on demand or close to it. If you marry him and try to avoid sleeping with him, after a while even if you married the most patient guy (and even if he didn't come from a culture where men feel they get sex without having to consider how the woman feels about it), you'll have to deal with sulks, anger, demands, or worse, and that will carry over into your marriage overall. Please do both of yourselves a favor, and gently explain to him that while you are tempted because you want children, you are not sexually attracted to him. He might surprise you by not caring, but it doesn't sound like it. You owe him that much of an explanation, and the chance to understand your feelings.
When you look for a car or a home, you look for cool features that shine and look important. When you look for a husband, or a life partner, you look for things like kindness, stability, caring, honesty, reliability, sense of humor, etc.
Those things matter so much more, and will help you get through really hard times, than a fancy education or important job.
That said, if you aren't attracted to him, and can't imagine having sex with him, babies won't come if you can't have sex with him. And sure, some people get married just to have babies, but then what happens after the babies come? Then you are married to this man you barely know for the rest of your life, and you aren't even sure you like him.
If you want to be a mother, can you adopt? Is that possible as a single woman in India? I mean, that sounds nicer than being with some man you kind of like but aren't really attracted to, right?
