i know of two women that either doesnt have a sex drive, or never had an orgasm.
do you ever get urges,get horny? do you masturbate? Is there anything that you like...rub, touch...
is your husband the only guy you've been with?
I've been with a few guys and one guy wont do anything for me whether he's big or small. then you'll meet someone else that will rock your world so good you can see stars.
i knew a couple who got into manasatwa because they had issues...which is bad.
since your married have you thought about seeing a sex therapist. try to do research on your issue on the net...this will give you free ideas.
