You're most likely missing and needing the intimacy with your husband. Sometimes nothing can replace a real human being that you love.
I am sure you must have known kegel exercise. If you kegel each other, you will get extra pleasure.It is to be done alternatively. when he squeezes you relax and when you squeez he relaxes. Both will greater pleasure. when you are alone do a female deer exercise. This will help you to masturbate and it will be a good exercise to address sexual problem.
Another way is allowing him to withdraw his penis keeping one and half an inch inside the vagina. At this place your grip on his organ will be stronger. This will make him happier with sexual performance asking you for mote. You may google -female deer exercise- kegel exercise.there is a reverse kegel exercise as well.
So you are satisfied by husband normally and I assume you don't have 10 orgamsms with him? Have you tried using a sex toy...vibrator, dildo?
