Genuinely not that difficult in the slightest. It's like saying you can't kiss someone because they're wearing glasses.
Unless someone is using those REALLY long spikes, you won't even feel it.
Although I can't lie, it's kinda weird of you guys to complain about an alternative looking girl wanting to look alternative... Gonna complain at the cheesecake factory that it isn't dairy free? Like you guys knew what you were getting into and there's plenty out there without the tattoos
