Here's an odd problem with myself getting fit that I didn't think I would have and would like to throw the question out there to see what you all think of it. I am 5ft 9in tall and currently about 145 pounds and 36 years old, and have always been rather slim. I weighted 120 pounds in college, so I have not really gained a lot of weight, but I have accumulated a little belly fat that has pushed me from a waist 28 to 30 in the past couple of years. This past fall, I peaked at about 150 pounds, and have been determined to loose the little bit of belly and love handles I've accumulated. I have been going to the gym and working out on both machines and free weights, along with doing plenty of cardio too. I ran track in high school, so I have been doing a few miles of running every few days to burn off some calories. I also ride my bike with my wife occasionally too. Along with that, I have cut out soda pop, white bread, junk food, sweets, etc, and have generally reduced my overall calorie intake. Although I've only lost 5 pounds, I have traded fat for muscle mass and really leaned up. Overall, I feel much healthier and much more energetic, except in one area...my libido. Prior to starting out this regimen, my libido was crazy...like I was still a teenager. I would get spontaneous erections throughout the day, and it didn't take much for my wife to have me fully erect. We could go at it several times a day, and I could occasionally be multi-orgasmic too. Well, sometimes now, I cannot just get it up, or I will feel to wiped out at the end of the day. Well, a couple of weekends, we have had family events going on. The most recent one, I was out of town for four days for my sister in-law's graduation, and did not get hardly any exercise. We spent most of our time either driving in the car, or sitting at events. We also ate lots of food at restaurants and banquets. Well, this time, as has been for the past few times I have broken out of my physical regimen and diet, My libido was back with vengance, My wife and I went crazy in the hotel room the past few days So, the big question is, am I over training, or is it that I'm starving myself and my body is reacting negatively to it? I always figured getting healthy would increase my libido, so why does it do the opposite?
