Okay I'll take a crack at this....
#1: Find out what SHE likes: I believe that everyone has something unconventional that turns them on. One way I've gradually eased in my tickling fetish with a significant other is to find out first what she likes, if not directly then by trial and error. I had an ex that I inadvertantly learned loved biting and to be spanked. Once she saw I was willing to indulge her in something like that, the tickling thing was accepted a lot more easily. Just exploring each others passions and fantasies in general will also bring you closer together as a couple.
#2: Never underestimate foreplay: Don't jump right into it by beginning with penetration. To gaurantee maximum orgasm, pay attention to every square inch of her body; licking, kissing, gently running fingers across their skin, teasing and sucking on the nipples, kissing around the neck, running fingers through her hair (theres a spot where the neck meets the hairline on the back of the head that I've found turns on many girls I've known) and then of course there's the little man in the boat....which brings me to...
#3: GET AQUAINTED WITH THE LITTLE MAN IN THE BOAT: Get reeeeeeeeeeeeal close and friendly like.....your girl will love ya for it. This, in my opinion is vital. I love performing oral sex on my girlfriend and she loves it too. Plus she often returns the sentiment later
😉 The actual spot you have to focus on is the clit, the little....well....I guess I can only describe it as a "button" of sorts (picture below). Tickling the clitoris gently with a feather or your tongue will slowly drive her insane.
#4: Pace yourself: When you finally do get in there, start off slow and rythmically and if possible, try to pay attention to other areas of her body while doing it. (if in the missionary position try sucking on the nipples and kissing around the chest/neck while thrusting or if in doggystyle, running your fingers up and down her back with each thrust.) If you get over stimulated/exited and think you may finish "early" then slow it down a bit and go back to stimulating other areas of the body or switching to going down on her (oftentimes doing this switch quickly and unexpectedly will heighten the excitement of the moment)..."What are you?.....oh......OH MY GOD!...." LOL
#5: New positions are always fun: As humorous as the images are, this is a pretty good sexual education based webpage with an illustrated list of various sexual positions:

#6: Toys are fun too: If you consider trying out certain "toys" see if she will accompany you to look for some as opposed to going out on your own. You might be suprised what she'd be interested in. One of my personal favorites is a small vibrator that fits around your finger. Simultaneous thrusting while holding that over the clit has shown to produce multiple orgasms.
I'm not sure how much of all this you'd be comfortable with with the Catholic upbringing, but just remember that a healthy sexual relationship is a vital part of any lasting relationship regardless of faith. What matters in the end is that you both enjoy one another to your full potentials as lovers.
On a side note, one of the most intense experiences I ever had was with my ex-girlfriend and another couple. We're swingers as well as both being bisexual and had a lot of fun with other people. One time (I actually think it was a birthday) we were all ganging up on my ex; licking, sucking, etc. By the end as a way of indulging my fetish, I was going at it missionary style while the couple, one on each side was each tickling her feet! Needless to say we both loved it....quite a happy birthday.
You can do the "fuckling" (as I've dubbed it) with just the two of you though, utilizing the legs up missionary position (second picture below) with some ankle bondage maybe. My ex described it as "sensory overload" but resulted in one of the most intense orgasms she'd ever had.
