Female masturbation- question.

Elizabeth
I am a Christian woman and I have never been able to ask about this to anyone ever! Is female masturbation wrong as a married woman? I never need to fantasize about anyone while doing it...it just feels right and helps to relieve stress. My husband just doesn't understand I need clitoral stimulation to climax. I know biblically it is wrong for men to spill their seed without a woman...but I have never had a clear understanding as a female where and if it is considered wrong in the bible. Just need clarification and scripture if I am wrong in this, thank you!!!
