I have been with a great guy going on 6 years, he knows I need much nore sex, intimacy and 1 on 1 time, he does what he can all the time to make me happy, such as: making lunch for me, helping around house, a lot of great "roomate helpful things" but not "I am wanting you" things! I am sad a lot of the time. We have sex once a month, and it lasts 5-10 minutes... I am so frustrated that I am in charge of my release... always!

There are the standard battery of questions:
1). What is his stress level like? Is it high. Does he work a lot? Is he a student?
2). How tired/exhausted is he?
3). Does he Masturbate a lot?
4). Have you asked him? He knows that you need this extra time, but you do you know why you're not getting it? Talking is the best way to find this out.

So being in this relationship for over 6 years, I assume you're both over 18. So why doesn't he he do this for you? You might want to ask him that.

How old are you?

Have you talked to him about this? Really sat down and let him know ALL your feelings?

Is it possible that you simply have a higher sex drive and maybe a toy may help you curb it for you?

And plus one to all of cravens questions.

Thinking about it a BOB might also be a turn on for him.
