Books on intimacy in marriage

Hi all, so my wife and I have been married for almost 5 years and we're approaching our mid 30s. Unfortunately, my wife has had some health issues (which within the last few months have been remedied) that have prevented us from being physically intimate and it's caused a lack of intimacy in other areas as well. Recently, by the grace of God, the Holy Spirit has really helped me to see how to care for my wife's emotional needs and to support her in the ways that help her to feel loved in other ways. But the fact of the matter is I know it is important for us to come together in the bedroom to prevent temptation according to 1 Corinthians 7. Unfortunately, due to the years of not being sexually active with each other, it's been really hard for us to find that spark in the bedroom. Are there any books that are biblically sound that you'd recommend for couples who struggle with sexual intimacy?

Thank you all.
