I wouldn't do anything until you come to terms with your tattoo. It's very nice and I've seen a lot of people make things worse, not better when they rush to try to fix something. I've never had tattoo remorse so I can't relate, but you have a really solid piece that will stand the test of time. It's not like you got a monkey humping a football, or something stupid. Even if you don't grow to love it, it's not something you need to be embarrassed about. It's solid work, a solid design and you should wear it proudly.
