keep faking orgasms with my boyfriend?

Erin
My boyfriend and I have known each other and have been hooking up for almost two years now. I am the type of girl who is unable to orgasm through penetration alone. I had a conversation with my boyfriend a while ago about how I had never achieved a climax this way before, but he still felt determined that he could do it for me. After a few months of him feeling inadequate and several times where we would start having sex and stop shortly after because neither of us was having fun, I thought I should try to fix things. I faked an orgasm and he now believes he is the only guy that has ever done it for me. I feel guilty about it, but now that I have kept the lie up for so long, I am worried that it is going to make it even harder to tell him. I didn't lie for me, I did it for him. I didn't want him to feel emasculated. I don't know what to do! Do I keep up the lie or just tell the truth and accept the consequences? 
Well let me just say, that the first part of mine and my boyfriend's relationship, I always faked it. And I felt bad. And at a certain point when I would get turned on with our foreplay, and never ever finish, it's drains you. It drained me to lie to him and I was so sexually frustrated. So for me, I stopped faking it. I just stopped one day.  And at first he felt ashamed because he thought he was bad. And to be honest... we were both pretty inexperienced. So it made me focus more and made him focus on me more. So it made sex for us more fun and no so... one and done. We have great sex now. We experiment, we have fun. 
I hope this helped anyone that needs some light on their sex life
