I really want a tattoo, should I go for it?

Yeah, I know this is totally up to me in the end but I'd like to hear some opinions.

It's like this.

I came from a Christian family and I'm from a country in Asia where Islam is the country's "official" religion My dad is a religious person but he's very open minded about things. I've never asked him about tattoos though but my boyfriend (who is the son of a fellow church member) has two tattoos on his forearm and they seem to be fine with it. My boyfriend's parents, upon seeing his tattoos for the first time, reacted positively and even said "It's okay son, we don't mind. It's an art after all."

It was a totally unexpected reaction to us since we (my boyfriend and I) really thought that they're gonna freak out or something because his parents are very religious too. We both came from different ethnics - I'm Bidayuh and he's Iban. The Ibans are well-known for their traditional tattoos, so I guess that's why his parents were not angry about it.

Now I already have two tattoo design in mind - one is a bible verse, Joshua 1:9, which I planned to do on my wrist. The second one is something bigger that I plan to do on my right arm. I really want to flaunt them, but I still have the fear of being judged by my church members and especially my own family members. I recall my grandma telling me: "I heard that your boyfriend has "scribbles/drawings" on his body. Don't you know that in our time, people fear those who have "drawings" on their bodies?" I thought it was funny and brushed it off but then on second thought, maybe she's saying that she doesn't like people with tattoos. However, my desire to have them is so strong and it's been really bothering me.

What's your opinion?
