I've never minded crowds, I do get annoyed when it takes forever to get a drink cause the bar is packed.
I especially like crowds when there is music playing live and everyone is enjoying it, or the vibe of a packed sporting event. Both have similar group "hive mind" energy going on. Went to a Wolfsburg vs BVB game when in Germany and it was packed and awesome, I was like two rows up from the locals drum pit.
Some tattoos I find add to a woman's attractiveness, my wife has thin vine going from her foot to ankle and I think it is very tasteful and looks awesome.
My best man at my wedding has a rib tattoo that looks like someone pealed back the skin revealing the muscles, veins, and such and it looks amazing it really fits his personality. It will no doubt look awkward when he gets old.
Most tattoos that would prevent a person from a job as a bank teller I dislike; face, hands, neck included. Any tattoo of a face looks like crap, I don't care who has it or who it's of.
I feel the same way about piercings, if it wouldn't prevent you from getting a job I probably find it attractive. I do have a fondness for nipple piercings, the simple bar type most of all.
That said I have nether and have no plans to get one. Would probably get a "13" tattoed if I did though.
