Here's the letter that inspired this episode:

"Hey guys, I have a situation I'm hoping you can help me with. I am 28, and have been with my boyfriend for 5 years. He just proposed and I said yes. The problem is, I've been faking orgasm for our entire relationship. If I'm going to marry the guy I want to be honest with him and work on having better sex. How do I tell him I've been faking without crushing his ego? Sex feels good but not great. I can easily have orgasms when I am alone, but with him I usually don't get all the way there. I've had a few orgasms with him, mostly during oral sex. But the rest of the time, I fake to get it over with. Should I tell him?" ~ Meghan
