So funny that you ask that, because beofre my husband and I bought ours we really wanted an answer to that question and couldn't find it anywhere!Sleeping on a Tempurpedic bed is much better than a regular bed, hands down. But I wouldn't say the sex is better, except that it's not as noisy no springs to squeak! (Our headboard still squeaks, though, so that benefit is sort of lost on us.)There is a difference between sex on the Tempurpedic and sex on a regular bed, but it didn't take us long to get used to it and now if we stay somewhere that's a regular bed, I can't say we really even notice the change. The biggest difference I noticed when we first got it was that if I was on top of my husband, my knees would sink in more than a regular bed. But again, after a short time we got used to it and now we don't even think about it.We've owned our Tempurpedic for just about 4 years now and we are still raving about it and commenting how it's the best money we ever spent, so I can highly recommend it. In our experience, it won't have much impact on your sex life.
