I'm going to go ahead and assume you're OK with some graphic descriptions since you're here already.
I've been on the SCD now for 2 months, and have had excellent results- down 30 lbs of weight and that's with some muscle gain as well.
I'm married (to a woman) almost 4 years now known her for almost 7, and we have a 9 month old daughter. Our sex life was fantastic for many years, through getting married. We even managed to have sex on our wedding night! (which I've heard isn't super common) things kinda tapered off after that, and then when we had our daughter someone shut the tap off. Coincided with a bunch of fat gain for both of us. Sex was a once a month at most prospect, I had trouble getting or maintaining an erection, and the result was a downward spiral.
well, the past 2 weeks have been different to say the least. I think that losing that fat had a tremendous impact on sex drive. She's also lost some fat as well (not as much as I, but still statistically significant). We've been having successful sex several times a week, sometimes several times a day, my cock looks bigger and erections are double-dose-of-viagra hard. Duration is great, and she's been having a lot of orgasms.
Why am I writing this post? Well, advice from the 4HB has vastly improved my sex life, and its not even from the 'Improving Sex' chapter. If you have some fat to lose, know that doing so will probably increase your sexual performance. Getting checked out by women on the street 8x as often after losing that fat certainly doesn't hurt either, and if I was single I'm pretty sure I could be landing some hot ass on a regular basis (damn, I still wish I was single sometimes).
