You didn't ask a question. You just told everyone the most irresponsible choice to get a tattoo and how you would take care of it the wrong way and possibly get some infection. You friend is not a tattoo artist if he is tattooing out of his home.
A proper sterilization machine costs about 2,000 dollars. It's actually NOT totally safe, it is totally unsafe and you will probably end up in some doctor telling this embarrassing story about how you let a child put a needle in you. Perhaps you need to grow up and mature some more before making a decision like this.
I literally cringed when you said you'd take care of it with sunscreen. Honey, to take care of a tattoo you need regular unscented soap and a non-vaseline based lotion or cream. Also needs to be unscented.
That's one indicator that you're not ready to have a tattoo. Second, a tattoo isn't a replacement for actually getting help for your problem. Seeing a picture online of a tattoo isn't a good enough reason to get one.
If you still want it when you're 18, then you should get it and go to a professional shop. Your friend sounds like a pervert if you're not even 14 and I would have to assume he's at least 18 to even be tattooing. Does he have a license?
If not, do NOT let him tattoo you. That's such a huge risk to take. You're too young to know what you want for the rest of your life.
This isn't a sticker or a wash off tattoo. You're at the age where you'll definitely be changing your mind a lot and you are WAY too emotional by the sound of it. Don't get it.
Wait until you're 18. Be smart.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
