Male Orgasms?!???!!?Apparently I need some sex ed!

TMI! So I've been married for almost three years and we lost our virginity to each other. Sex feels amazing for both of us, we talk about it a lot and hubby never complains only talks about how happy he is and we try to think of new things ever so often but... I feel so embarrassed for asking but is ejaculating and having an orgasm the same for men? I mean, do they get orgasms when not ejaculating? My hubby never lets out any noises, never moans, only sometimes he just might whisper how good it feels or moan very quietly i barely notice. I feel bad, even though I know he says he really enjoys our sex life i feel like there might be a lot more to it than he's receiving from me?! Any advice and please enlighten my knowledge, lol?!?
