First of all - how old are you?
If you want to look aesthetic - of course you should keep your body hairless, but there are such important things as:
- For the first time you should shave chest with razor.
- Since you are pretty tanned - you need to tan in solarium the day after shaving. You may use cocoa butter before tanning.
- If your body grows hair not so fast, so you can shave just once-twice per two weeks - you can shave with razor only, otherwise - use cream/gel/anything to cause hair falling.
Noticeable, you have great genetics - you should go to gym and workout a little to add some fit look to your body.
Its kinda like +2 to your overall look in 10 point system.
Cheers.
