Okay, here is a tip for helping your boyfriend understand your predicament (which, by the way, is so common that the MAJORITY of women have the same experience as you...including me)
Say to him that your clitoris is like his penis....in fact, it is very similar. You need to have it stroked in the same way he needs his penis stroked or touched in some way, to reach orgasm. Tell him that to "try" to orgasm without any clitoral stimulation, would be similar to you asking him to "try" and orgasm from JUST having his balls stroked, or his perineum, or his nipples. While it is still possible he/you can orgasm from NOT touching the clitoris/penis, it is not that easy and not everyone can do it.
It is important to get this message across. Maybe ask him how he would feel if, for the next two years, you constantly kept asking him to stop touching his penis and get himself to orgasm by stroking his balls. Ask him how he would feel every time he failed to reach that orgasm, when he saw disappointment on your face, or saw that you were desperately seeking something he could not do. Explain how this can eventually leave you feeling.
Only about 30% of women can orgasm during penetration and I imagine that for most of them, it is because they are experiencing indirect clitoral stimulation (like, maybe his pelvis is brushing her clitoris)
When you say you are only using your vibe once a week (quite unfair right) do you mean he has banned it from use the other 6 days of the week? I just get a sense that he is expecting you to be like some porn star and that you should be able to cum within seconds of him penetrating you and that only his body pleasuring you directly, counts. Like, its not a "real" orgasm if you got there using a sex toy instead of his penis?
Unfortunately if this is how he feels, then I believe he is insecure. Not his fault. He probably feels like he is failing to be "the man" when he cannot make you orgasm and a sex toy can, but unfortunately I believe this is an issue he has to deal with, as opposed to you being denied pleasure to massage his ego. I sympathise with him, but I think he has a misunderstanding of female pleasure, how much more difficult (and longer) it can be for us to reach orgasm and the fact that MANY women simply cannot orgasm at all unless they use vibrations.It really has nothing do to with how much you love him, how much you area attracted to him and how much he turns you on....it is just how your body is designed. I hope he can understand that.
Ideally, he needs to see the sex toy as an extension, or addition for spicing up your sex life together, as opposed to a threat. It is an inanimate object, a tool, a device and could never be "better" than him.
