Good grief! I agree with Kazz on this one – if you are that easily swayed then and especially by someone who makes a general comment that is not knowledgeable about tattoos being “tramp stamps” then you’re right – tattoos are not for you.
I am 40, got my first one at 38. Age makes no difference – being a mom (I have a 14 year old) makes no difference.
But if you are the type of personality that worries about what others think then a tattoo is not for you, if you are asking us on here what a good one would be that you could stand for the rest of your life, then tattoos are not for you.
Once it’s on you, it’s on you, so while it’s too bad you were so easily swayed because I think it’s wonderful when older women get tattoos, you definitely should not get one.

Go back to your tattoo parlor and get their advice. I have 5 tattoos and all I have ever used after is Lubriderm lotion. I’m usually done with the peeling, etc. after a week. But all people are different. Your best bet is to go back and have them look at it and get their advice on how to procede so you don’t do further damage. And don’t worry. Any reputable artist will touch up your tattoo for free.

When I read your question I knew you’d mostly get supporters responding because those who generally respond negatively to tattoo/piercing questions do so just to give an opinion about something that has nothing to do with the question asked. When out right asked what they think they don’t seem willing to step up and say why because they know how they will come across.
The biggest thing I’ve learned since getting tattoos is to never judge a book by it’s cover.
Enjoy life while you can with no regrets!
