I really like my boyfriend, but he has girly tendencies...?

i really like him. he's the only person i know that thinks as weird as i do, and can carry on conversations about weird things. he's sings and writes and plays the guitar, which is definitely a plus because my life is super focused around music. he treats me like a princess, we get along super well and i've never met anyone like him. buuuuut, he has really gay like mannerisms, and growin up in a family of 4 boys, i've always expected boys to act like boys. he covers his mouth when he laughs, 'bent wrists', gets really giddy if i do somethin he thinks is cute, and makes girly noises, kinda swings his hips, and other girl like things, and it's really annoyin. i've tried joking around about it to get him to take a hint, but he doesn't .... he just does it more to bother me in a joking way. i'm not good at confrontations either.....what do i do? and is this normal? howw do i talk to him about it?
