for example I plan on getting a tattoo on my chest and my Friend who has a few tattoo (none on his chest) said it would hurt less because I have more muscle, but what does he know about that? any way would it hurt less if i were flexing my chest or does it even matter.
I looked up some information for you:
“Generally, the tattoo is more painful if applied to areas of the body where there is less muscle and fatty tissue covering bone, like wrists, ankles, chests, and other normally sensitive body areas. Upper arms are usually the least painful, while the ankles and sternum can be quite sensitive. As a rule of thumb, any part that's too ticklish is likely to be sensitive, hence, painful. But as I said, it varies from person to person.”
Decide what part of the body you would like your tattoo. This will determine the level of pain. Getting tattoo over bone or over a portion of the body where the skin is tight hurts more.
Gauge the tattoo pain in the context of your life experience. If you're young and haven't experienced much pain, then the tattoo will probably hurt quite a lot. If you've experienced great physical pain, such as childbirth, the tattoo pain will pale in comparison.
Try relaxation techniques such as deep breathing and deliberately relaxing muscles. The tenser you are, the more the tattooing will hurt. Breathe in through your nose, out through your mouth and try to think of something else.
Watch for the endorphin rush. About 15 to 20 minutes into your tattoo, you'll notice it starts to hurt less or stops hurting completely. This is due to endorphins or your body's own natural painkillers.
Consider using topical anesthetics for cosmetic tattooing. However, if you're getting a tattoo as a piece of art, most tattoo artists won't use these.
** I don't recommend step 5
Remember what the tattoo artist is doing. They are puncturing your dermis (second layer of skin) multiple times with a needle. By putting the ink deep into the skin, it becomes virtually permanent. This doesn't feel good.
Moral of the story is don't flex… relax… and depending on your piece it may take a long time to do…
…Can you flex your chest for an hour straight?
Get comfortable, remember to breath and relax and it will be over in no time.
