Hey Shion, I can tell you that I clip and or shave my chest, back, torso, and pubes. I think that it makes a big difference in the way one looks. Even when I have been overweight, it has made a difference. Here is what I have noticed, clipping the pubes with a #1 comb makes me look quite a bit bigger down there, girth wise probably more so than length. As far as clipping your chest and abdomen, here is what I came to the realization, I hope I can explain it properly. When you are overweight, and you have any love handles or fat rolls of any kind, when you look at yourself in the mirror, the thing that makes them really stick out, seems to be the shadow that is under that area. I read your an artist in your bio, so you know the power of the shadow. By shaving / clipping you remove the hair and make the whole area much lighter and thus you will look a little bit trimmer. Also, the smoothness that now shows, gives the impression of trimness. When you do shave / clip your torso, be sure to leave you treasure trail in tact, as that is a wonderfully sensual thing for others to be able to see. Shave your back. There are few people that will want to have a man with a hairy back.
Women that I work with, have said, that they want their men to be 'manly' and have armpit hair, but, they don't want to see it when it is not appropriate to be seeing it. So, simply trim your armpits, so that no hair is seen when you are wearing short
sleeve shirt.
And my finale is this. The nape of your neck. Shave it! When I am looking at a guy, and trying to decide if I am interested or not, I always look at the nape of his neck. A guy that pays attention to this detail, I have found, really does care about what he looks like, and has an interest in keeping himself up. It is not just your barbers responsibility to shave that 1 time a month. You need to run a razor across that at least once a week. I have discussed this with women that I work with, and they all confirmed that they look at this as well.
If you want any tips or further questions you can email me, I will be glad to discuss the things I have learned over the years.
