Need some help

I am a (15F) that is sexually active. I know I am pretty young for it but it’s wtv. I have had sex with my (15M) bf.( lost my virginity to him)There’s a problem tho. Every time I have sex with him I don’t feel anything. I let him do whatever he wants during sex because either way I don’t feel nothing. At first I started doubting that it was me. then I remembered that I simply do feel pleasure with two small fingers so it couldn’t be me.Then I thought it was because I wasn’t tight butttt there’s times he struggles to put it in because of how tight I am. But still the doubt is still here. The only feeling I do be getting rarely is just pain. I used to get horny when he would kiss my neck suck on my breast and stuff but when it came to having sex I just ended up getting bored. I have to pretend that I like it and have to fake moan. I act like I want more and I haven’t told him anything because I know it would really mess up his pride and I’m not going to do that. Now it’s so difficult for me to get horny with him I try to get horny and I just can’t even when he does the things that got me horny before don’t work. It’s like if I have lost all desire with him. I keep having sex with him till this moment just it’s hard to get in the mood. The thing is that I’m a very like horny person just that idk this is happening to me out of the blue. I don’t know what to do because I also want to feel good I don’t want to keep faking orgasms and fake moaning.i also try to get in a position ones in a while to see if that’s whats the problem but it doesn’t work. Any advice on what I can do to solve this problem ? Pls don’t judge!!!
