I cannot recommend the book A Celebration of Sex enough:
https://www.amazon.com/Celebration-Sex-Enjoying-Sexual-Intimacy/dp/0785264671
Someone recommended it to us before we got married and I'm so glad we read it. Hubby and I both learned things about the opposite sex we didn't know...and even things about our own bodies we didn't know!
It's written for Christian couples who are totally new to sex.

Is also a great resource for breaking everything down and troubleshooting.
In addition to everything else that's been said, get these books and read them together:

I've not read the first one, but it is often suggested in these situations and has really good reviews.
The second one was suggested to my wife and I by our premarital counselor. It talks about the different ways couple's communicate love to each other, and one of those ways is through physical touch and intimacy.
You also might try posting this in one of the Christian subreddits to get some representation from that perspective.
