How to spice up a relationship without intercourse. (Abstinence Q’s)

Hang tight with this one....

So my boyfriend (22M) is waiting until marriage for sex for religious reasons. He is a virgin and has only ever made out, and fingered a girl once. I don’t think anyone before me gave him a hand job but that’s unclear. When him and I make out, some dry jumping occurs and he cums from it almost each time we do it. I (25F) am not a virgin and have done almost all of the things. Agreeing to abstain from sex in order to date him has been the hardest thing for me, but I’m willing to try for him because he’s honestly the best guy that I have ever met. I want to make it all work.

He’s actually an incredible kisser, however I’ve been craving more from us and what we do and I’m worried that I won’t be happy if all we do is make out for the next however many months/years we date. Giving up sex cold turkey was hard after doing it regularly within previous relationships. I’ve been trying to think of ways to spice us up.

He confided in me saying that fingering a girl scares him because he just doesn’t know what he’s doing. I’ve offered him many times to just sit down and help him and show him how things work down there. No pressure and all - he knows I care deeply about him. He claims he feels bad that he hasn’t made me orgasm yet and I keep telling him we have time... But I’ve been telling him for weeks now we should sit down to figure out how it works and we just never get to it. I don’t know if he genuinely forgets, or he has no interest in learning, or is still really scared.

I gave him his first hand job a few weeks ago and he really liked it, he actually moved my hands towards him to do it, it went well! (I didn’t think anyone actually liked them) I want to try giving him a blow job soon but I’m afraid to scare him.

—> How should I approach this? I’ve been wondering that if I show him how great and how comfortable he can be during oral or just during moments of physical intimacy, he will be more relaxed and willing to learn how to please me.

Does anyone think that will work? Or other ideas to move us forward in our physical relationship? Also, how should I bring this convo up?
