My partner and I enjoy keeping fit and both of us get the occasional compliment from a random woman or man.
Although it feels nice to receive compliments from others, the main reason why we stay in shape is for ourselves. Living life to the fullest and enjoying the beauty, for us, means feeling good about ourselves -- not how others feel about us. If we can make someone smile with the beauty of our sensual bodies, that's just icing on the cake.
Genuine compliments from others are always nice. Sadly for me, I very rarely get them. But I'm out of shape, so it's little wonder that I don't get compliments from people, particularly from women. Training makes me feel good -- I'm always pumped during and shortly after a workout. Additionally, it increases self-confidence, for which women seem to have a sixth sense at detecting, like a shark being able to detect a drop of blood in the water from miles away. And from what I've read, women dig men who can "step up to the plate" with their heads held high, not some dude with slouched shoulders and his head down when talking and walking.
Right now, my self-confidence is not great, but training is, as mentioned above, helping me. I'm dropping weight, and as of this morning I checked in at 212 lbs, which is still too heavy as it's mainly fat. If I were 212 lbs at 12 percent body-fat that would be different, but my waist is too damn big. I'm in a conundrum right now, as I'm the dreaded, so-called "skinny fat"; I have a beer gut and man boobs, but thin limbs. Kind of like the stereotypical alien (I also have a long horse face, which doesn't help). But I can't change my bone structure.
This is getting verbose, so for the sake of brevity I will adhere to a stringent diet and exercise regularly and see how far I can progress after a year of training.
