Me personally, I think that if both of you are fine with it, then cool. If you come into a relationship, knowing that the other person despises it and doesn't want it looked up, and you agree with it, but yet go behind their back and look it up anyway, then it's very dishonest and the question will come up of why get with someone who you know has an issue with it. I personally also feel that it's detrimental to a relationship and sex life especially if one person strongly opposes it. Hope this answers your question.
