Vibrator vs husband

I love my husband so much and i didn't marry him for sex but lately I've found myself having to lie about how good our sex life is very often and i mean OFTEN. AND he doesn't know this but I've never came...NEVER ( lost my virginity to him only man I've ever sexually been with) i bought a vibrator just to help US but lately when he's not home i use it and for the first time i came and it felt amazing but ever since that night when he tries to have sex even when he kisses my neck to try and get me started i immediately get irritated and upset like heres another day of sex where he's the only one enjoying himself he nuts always we've been together 5 years married for 6 months why is this happening??? I'm really trying to be into it but it's like i want to be pleasured too. Hes terrible at fingering and eating me out but nuts after a few minutes when im going down in him its not fair...like u said i didn't marry him for the sex he's an amazing guy and it didn't bother me at all before but for some reason it's slowly getting to me and to clarify his dick isn't small it's 9 1/2 inches and the vibrator only Caters to my clit it's not the kind that you stick inside but in the beginning it was amazing i guess because he was my only
