HELP!!! I can't , just and I'm a girl.?

Please don't send this in for abuse, I have an honest question I can't get an answer from anyone about. I'll try to watch my language. I am a girl. I have a personal problem. I havent' climaxed in two years being married, and we've stimulated the c* lots. So I tried the vibrator (homemedics mager)several times but all I got were v* ejaculations, not anything like the c* s I keep hearing about. I don't feel relaxed or spasms or anything, etc. I just get really really tight and never release, just sometimes ejac* lots and then it goes all over again. Any advice on how NOT to just have what I'm asuming as a g-spot orgams, and have the c* ? Should I try a certain position better to stim* or a different vibrator or what? This is a serious question. No rude remarks or jokes please.
