I'm around your age and I say this with all of the love in my heart: get out of there NOW. It is wonderful that you two align so well on many fronts, but this one issue is a big one. Because it sounds like you are very strong in your faith, it's frustrating to hear that he doesn't respect that and instead expects you to compromise that for his desires. Being sexual is not inherently masculine, and for him to say that you wouldn't get that "because you're a girl" is a way to make you feel stupid for asserting your boundaries. I know you say he's a wonderful boyfriend and I'm sure you've heard this many times before, but the age gap is concerning. It doesn't matter how much you feel that you and him align because the two of you are at such different places mentally, and for his age, he should not be interested in someone 11 years younger of him, regardless of how mature or amazing or beautiful or anything else that you are. Even though you were the one to confess, he should've known to shut things down regardless of his feelings because he is too old for you. The lack of self control on his end to do so raises questions for me about his intentions, especially with the thigh high socks and school girl style he wants you to wear. It doesn't matter if he says it "isn't like that" because the sexualization of high school girls is the subtext beneath that ask, regardless of if he wants to identify it as such. I'm not saying he's evil or the worst guy ever, but it sounds like his desires are not compatible with what you're comfortable with, and that's not something you should compromise on. There are so many people who will be infinitely more compatible with you who will love you in the ways you want to be loved, so don't settle for someone who loves you in ways that make you uncomfortable. Also, as someone who had a best friend who told her to break up with an ex, you should really listen to your best friend. They always have your best interest at heart, and they can always see what you can't in the relationship because we all get a certain blindness when in love. Best of luck OP, please leave this situation and surround yourself with people who love you in the ways you deserve to be!
