Is it wrong to want more ?

My boyfriend and I have been together since March of 2015 , he’s my first boyfriend , my first kiss , my first everything . And I’ve always been the one who craves attention , I’m a flirt . I didn’t have it growing up so when I get compliments or when someone flirts with me , I just flirt back . I do it without notice . And I always try and hold back because I don’t wanna disrespect my relationship in anyway .

My boyfriend is a really quiet person , he pretty much ignores me when I’m around , & it’s not that he’s on his phone or whatever but he’ll just be lost in thought . So I always feel neglected . And when I bring up how I feel it starts a fight .

& in sex there is no intimacy , and that’s all I’ve been asking for , but he just gets right into doing his thing .

And I don’t know how to feel , I want more than what he’s giving me but at the same time I don’t want to lose what I have with him .
