trouble in paradise

so i am 17 & my boyfriend is 15 & i have been dating him for 2 months now & last month i addressed some issues i was having (since he is so young he isnt very mature & he is just really self centered) i told him what i was feeling so he is sorta trying to fix what he is doing. but im honestly really not attracted to him like i was before. i feel like im really letting the age difference change my thoughts on him 🤦🏻‍♀️ idk if i should stay with him & see if anything changes within myself or if i should just end it before anything big happens. Ooh & he wants to loose his virginity to me on his birthday ! im not sure if he knows it i think he does but im not a virgin anymore & i honestly wouldnt feel right taking his virginity if im not feeling him like he is feeling me :( what should i do yall :((
