Hmm, I have a lot of tatoos my bf has none. But even though I have some large and kinda out there ones I'm not a person who ever asks someone of they have any, nor ask about ones I can see. I don't know if I really notice them that much and I don't notice mine much at all. They are just there and sometimes I forget they are there. Even a tiny one that is near my eye. Most people I know don't have any either.
I got a tattoo of my head being stitched on when I was pretty young, I am 34 and I actually don't regret it. It's funny..people will ask about my other tattoos and that one people usually don't ask or say much, and if they do they keep it short and sweet. I don't have to get into the meaning..but that particular tattoos meaning has transformed many times over as have I.
Its just one form of expression, to me it's not a big deal to have or not to have. I am a very visual person, I paint, create things, anything that is a visual art or craft picks my interest, so in that case it makes sense to gravitate towards visual self expression. However I wouldn't say my tatoos are emotion based, life stories seem to be what a lot of tattoos tell, so the temperary emotion thing might not be to accurate for many people but might be true for you.
But ... why post about it to stir the pot? Seems like a more interesting question than .. what do your have tattooed and why or why not, to me at least. What I mean is that you said you are bored with the posts, and an interesting thing to look at is how you respond that and what might be a more congruent way to deal with boredom. When you say " don't hate me" I hear..I am not totally comfortable with this either. Just wondering cause waiting for the backlash followed by an eeek

doesn't sound very fun.
