Sexually frustrate 🍆🍆🍆

This has been going on for a few years. Yes, I know! It sucks literally ☹️. I tell my Husband all the time that I need sex more regularly and he always says he's fine with having more sex but it always turns into once every 2 to 3 months of one time sex. We gotten into a lot of arguments regarding our sex lives. I have never been one to refuse sex when he is in the mood. But when I ask for sex it's like asking a favor. It's to a point now where I have purchase a vibrator to ease my sexual tension. I would like to hear if anyone has been thru this or has any advice? I've tried everything that I can think of to spice up my sex life but it always falls on death ears.
