First relationship and first post please help 23f with 23m for about 1yr

I (23F) have been in an about 1 year long relationship with my boyfriend (23M) .This is my first ever relationship and he is my first for everything, he has had a few serious relationships before me. I am not insecure about his past experience or my lack of experience. He is a good partner and a respectful guy. I don’t think he’s the kind of guy to only take me seriously because of my “purity”. However there is a part of me that feels the relationship is imbalanced. I feel like I have given him a part of myself he could never give me. A devotion that could never fully be reciprocated. I worry that he might feel more secure with me because of that and the fact I have no one to compare him to(I know no one should be comparing their partner but I just don’t have the lessons from past relationships others do if that makes sense). I’m not interested in a “playing the field” or “other fish in the sea”, but I just feel like things aren’t felt the same way in my relationship because of my lack of experience. I love him and I know I am happy with him, but there is a part of me that feels I’d always feel unequal if I “one and done it” with a man who has had more relationships than me. I hate feeling like this and would really appreciate some help. Anyone with similar experience can you maybe tell me how you got over this or share your experience as well? I don’t know if I should bring it up to him, but for those who read this I’ll take advice, words of wisdom/encouragement, positive affirmations, similar experiences, or anything y’all can offer. Thank you for reading and helping!

TLDR: I’m (23f) not sure if I feel equal in my relationship with (23m) because of our difference in experience. He has more past experience and I have none.
