I have a quite a few, of varying quality and meaningfulness, and I have to admit there's more than a little regret with some of them. Rather than ever having a coherent design plan, I had individual pieces done by a bunch of different artists over a 20-year span as the desire and finances permitted. It's sort of nice to be able to track my life through them, but I'm not really thrilled with the patchwork effect when they're taken as a whole, plus a couple of them are really kind of ugly, and most will be less-than-optimal fits with the female self I expect/plan to express. If I find the right artist, coverups might be an option for a couple, and I can probably come up with a design that integrates what's already there into something more cohesive and feminine, but truthfully it's not something I feel enormously drawn toward at this point in my life. Plus, it's expensive, and I'm socking my money away for directly transition-related things. Maybe someday.
On the plus side, years of experience under the tattoo gun make the electrolysis probe feel (mostly) like a walk in the proverbial park.
