I like tattoos and think that having them just outside the pubic area is sexy -- hidden from others (unless a bikini is worn) and the skin there doesn't stretch much with body movements or as we age.
It wasn't until recently that my wife started doing this to me. It is a big turn-on, for sure. She hasn't gotten to the point of sucking on them, yet ... one day, I hope.
I've gotten my wife to take delivery of pizza wearing a blouse thin enough to show that she wasn't wearing a bra and it really turned us on. Some videos that we have seen (amateur) that show the woman 'accidentally' drop the towel she was wrapped in when the pizza guy hands her the pizza are a big thrill for me.

The best I've ever had my wife do was to not wear underwear. I agree with others -- it's probably a fantasy of almost every guy to have his girl do this. Would be even more exciting if she told him she had nothing underneath, but they went shopping or something before he could see.
I would love for this to happen. I have tried a number of times to get my wife to like the idea, but no go, so far. It is sexy in so many ways. Watching her have pleasure / fun; having my own little sex show; getting to enjoy 'sloppy seconds'; and I would love to take him in my mouth and taste my wife on him.
