Oh well there are a couple questions here. First, what it be a huge turn off for me? No. I would be more concerned about it impacted anal sex than something stupid likely being a turn off. It’s essentially like having a mole. Honestly, my big turn offs tend to be related to personality more than physical but obviously there are limitations to that as well.
The other question is whether or not you should get it removed. My personal philosophy on anything cosmetic is if it’s going to make you feel better, then you probably should do it. If it’s not a big deal to you, then don’t. Only you can answer that question.
Since it’s weighing on you enough to ask me about it I’m guessing that it bothers you and so because of that you probably should get it removed. It’s the same thing with the idea of getting a nose job or breast implants or even something as small as highlights in your hair.
If it’s gonna make you feel better about yourself, then why not do it.
