"I know this may sound extreme, but my opinion is that the main purpose why we're on this earth is to worship Allah. Everything else is should be secondary."
and I was just stating how worship isn't limited to only prayer and fasting. You can perform different types of ibadah without them being seen as being less important. Their importance may be prioritized by individuals but there are many forms of worship.
I assumed that you had normal libido and was just stating how marriage, working, or studying are all rewarded (
it's not a must you do them just giving examples
) and they don't have to be seen as a distraction or waste of time from your deen. They can all be ways to enhance your deen and service to the community. Looking at it from another perspective, the mothers that had high libido before marriage and wanted companionship, may feel that marriage allowed them to better focus on the deen instead of giving focus to their distracting desires that they couldn't do Islamically until the marriage.
If you feel that marriage isn't for you then it's fine especially if you're asexual. There's more than one way you can be of service to Allah and the community. Sorry if you felt offended.
