What sort of a relationship are the two of you intending on having? Platonic or romantic? Because the two are quite different. Those involved in platonic relationships do not go on and marry their partners.
The lack of sexual intimacy although common amongst some couples, often leads to satisfaction sooner or later. If you have healthy libido and she does as well, at some point either one of you may find the need to act out on it. Even in couples where one of the partners became a paraplegic, their partner continues to have sexual needs.
On the other hand, if the two of you abide to a spiritual/yogic practice/philosophy and want to lead a life of celibacy, the issue is different. Romance and sexuality are interconnected. It is possible to build sexual/physical attraction. You may explore NLP (neurolinguistic programming and hypnotherapy as therapeutic aids) Both of you may want to talk to others in the same/similar situation.
