@kpatcox84,
I don't normally share this much about myself, but maybe I can help a little here so I will.
My situation was similar to yours when my wife and I first married. Both of us were virgins, but I was a bit more savvy (not quite the right word) when it comes to sex. Anyway, my wife was pretty much missionary only for a number of years and never really seemed to enjoy sex. If I did not initiate, there was no sex. And even then, she would often use an excuse to avoid sex, to the point where it began to hurt our relationship. But one thing I was certain about. I loved her and was not willing to let a sex issue drive us apart. She really was not one to talk about sex, so I started doing some reading. And then I began to realize that maybe I was part of the problem. I was into the sex for me and just did not realize that she was not enjoying it because I was not making it good enough for her. And she was not the type of person to talk about it or take matters into her own hands, if you know what I mean.
So, I determined to read up and take an evening of simply giving her pleasure. Forget about me, concentrate on her. I lit the bedroom in candles. I took her out to a nice romantic dinner. (Before I lit the bedroom in candles. lol) And I told her that the night was only about her and her pleasure. She was to simply relax and let me take care of her. I believe that evening she had her first real orgasm. And once she realized what that felt like and that I could indeed make her feel that way, she became much more receptive to sex. Our sex life got much, much better. She became more willing to try different positions. Now, she still is more comfortable with missionary, but that is ok. For her, that is the bread and butter of sex. Every now and then we try steak, and sometimes it is good and sometimes not so much. But bottom line, making sure she was satisfied made sex even better for me, even if it was the same old missionary position. Our relationship could not be better and we will celebrate our 33rd anniversary this Friday.
Why did I share all this? Maybe, just maybe, as good as you think you are in bed, maybe she is not quite getting there. So maybe, just maybe, spending an evening making it all about her and her pleasure will spark something in her. And then, if she becomes more active in her lovemaking, trying some wild position will not seem as important to you. By the way, I seem to remember reading somewhere that most couples only regularly use 2-3 different positions, so don't get caught up in the number of positions. Bottom line, stick with what makes you BOTH feel good.
Good luck to you.
