Never Orgasmed

I have never orgasmed. There are times I have gotten close when my partner goes down on me or when I'm on top but I usually get too sensitive and have to stop. It's so frustrating to me but he tries his best and I know it's mostly me. I've read all kinds of tips and articles but I still can't. I don't like to maturbate because it just doesn't feel as good as when my partner does it and I don't really like the feeling. At this point in our relationship when we have sex, he'll cum like 2-4 times and I can tell he's disappointed that he can't make me. He constantly tells me he will eventually. Honestly, I don't even know if I can and I'm just considering faking it. What are your opinions on faking it? I don't really know what else to do at this point.
