I’d imagine that not having a tatto is the sign of being a true non-conformist nowadays.
My second son’s GF has a large tatto on her back. She spent months designing it and considering it and it has great meaning to her as a symbol of a good friend who died by suicide, to her life, not to her death. She considers it a work still in progress. I very much respect that.
My wife spent months working with someone designing a small one, sort of a mandala design, for her shoulder for her 50th birthday; her present to herself. Unless something is going on I don’t know about it wasn’t to attract anyone and she knew that I am at best neutral on the subject with a very slight distate for them if anything.
So far neither of my two adult sons (or teen aged son, or, of course, 10 year old daughter) have any. The adult sons have had no problems developing serious romantic relationships. They may get ones in the future, or not, but if they do I will mock them if they get ones that have no significant meaning to them.
But then they have always been their own people.
