This is an interesting one for me - I definitely grew up in the era when tattoos were something you got if you were (1) in the merchant marine/navy/marine corps; (2) were in a biker gang; (3) had been to prison. Some of my high school buddies then got tats that we thought were so 'daring' at the time - and they are a brushtroke compared to what we see now. Then I started working with some younger people who had very large, very expensive, personal tattoos - and realized it was a generational thing.
My issue with tattoos now is in some sense the message - which is personal to each person of course (and often it's just 'yeah I thought that was a cool design') - but I've been attracted to some guys who have tats that are clearly or subtly satanic (pentagrams, goat's heads, etc) and I just can not and will not 'go there' with anyone who has that sort of message on their bodies. I think this might be dense/unfortunate because it could be that such is NOT the intended message of the person bearing the tats.
