Short answer, no. God gave us the gift of sexual attraction to enrich and strengthen our marriages. Though attraction isn’t the MOST important thing, it is important. Our bond and union is supposed to be physical, intellectual, and emotional. Sex isn’t an optional part of marriage, nor is it supposed to be an obligation, a duty or a burden. God places good desires in our hearts for good reasons.
Long answer, attraction often develops over time. If you really like someone and spend enough time with them, it is possible and even probable that attraction will grow.
It won’t necessarily feel like a teenage crush, or like you can’t control yourself, or that sex is always at the top of your mind. Attraction also doesn’t mean that the other person needs to look like a movie star (neither do you!)
Attraction to a particular person is actually not dependent on whether the rest of the world thinks that that person is objectively attractive. It is something between two persons that others don’t have to feel or understand.
The intensity of attraction may depend a bit on your natural libido. It will fluctuate with tiredness, health or hormonal issues.
But you should like to feel that person’s touch, and feel a desire for more and more physical closeness, even while being careful not to cross boundaries that are reserved for marriage.
If over time and deep sharing and meeting of minds and hearts, you feel zero attraction, no interest in a physical relationship…Please don’t marry that person! It’s not fair to them and it’s not fair to you, and it may be shooting your future marriage in the foot.
An important thing to keep in mind: Have I spent enough time with this person to give myself a chance to know them more deeply, to relax with them, to play, to share, to foster intimacy? If you haven’t, and if everything else seems right, resist the urge to make a snap judgment. Take the time you need, and don’t let fear rush you into a decision.
