when I got together with my current wife in 2005(we are both 53),I have sleeves and a good part of my legs done & a neck piece,my wife liked mine but did not have any tattoos at all,but ! since being with me & our son & daughter in law were getting tattoos too,
my wife,miss "I like yours honey but I will never get one",in 2009 when our first grandchild was born,she surprised me with "I want a tattoo honey" ! so now she has a descent size ankle tattoo with both our grandchildren's names and worked on twice now.
to answer one of the questions,it never did effect our relationship in any way because she had none and I had many.
IMO if two people REALLY love each other,each has to accept the other one and respect them to make it work.
I think tattoos on women are very sexy,but I thought my wife was sexy with or without tattoos ! :D she's a hottie !
