No drive for sex I’m young 22

So this is hard for me to talk about but I love my boyfriend deeply but I just don’t want to have sex not even the urge to. When we try I just want to get it over with and i don’t know why I feel this way he’s my best friend but the sex is not always great with him because he’s on the smaller size it’s hard for me to feel it. We have tried oral and fingering but again I have sensitive vagina and boobs so I really just hate being touched their this started when I was about 21 and now we haven’t had sex in almost 3 months I just feel bad like I’m not doing enough for him , he’s my boyfriend and I love him :( is this normal for my age? I started having sex at a younger age and I feel maybe that was my peak time. Or am I just being to hard on myself. Please help any advice on how to feel confident and how can I want to have sex again. I don’t wanna loose him.

Thanks girls xo
