Regardless of your gender or age, I'm going to answer your question because letting you make a stupid decision about something this big would not be cool, and because maybe you just don't know the first thing about modifications.
My experience has been really positive since getting my nipples pierced. My earnings have gone up all across the board and apparently lots of people dig them. At least the people who speak up anyways. I haven't heard anything negative about them yet. Getting my nipples pierced hurt SIGNIFICANTLY less than breastfeeding. It was really, really fast and I almost didn't even feel the first one. After care has been easy. I wash them with unscented soap and wore really tight sports bras and breast pads for the first 2 weeks to avoid catching them on anything. Pretty standard and fairly easy after care. Much easier than oral or ear piercings from my experience. YOUR EXPERIENCE AND PAIN LEVEL WILL BE DIFFERENT.
Technically you can't get your clitoris pierced. It's the hood that would be pierced. As far as I know, no reputable piercer would pierce a clitoris. I would HIGHLY suggest you do research on the subject before making any body modification decision.
This goes for guys or girls. Research the process, after care and need to knows, plus your local shops. It's also pretty smart to go in for a consult to check the place out before getting any kind of modification. Things to take note of: is the shop clean, do they have certifications posted, is the equipment sterile, do the artists wear sanitary gloves, do they have a gallery of any kind with previous work, do they answer your questions about after care/possible dangers, do they check for id, etc. The last thing you'd want to do is walk into some random shop and get pierced with dirty equipment and lose a body part or something. I started getting body modifications at 13 years old and have always been selective with who I choose to the do the modifications. Being picky isn't a bad thing, it's just smart.
