I need your guy's opinion on the pros and cons of getting certain piercings.

I want to get a couple piercings but I'm not quiet sure what the scarring would look like if I were to one day down the line decide to take them out. I want to get my tongue, nipples, and stud above my vag (can not think of the name at the moment) done. I've always wanted a tongue piercing that it was badass and just really cool. I want to get my nipples and my vag pierced because I think it is super sexy and I really just want that type of confidence an sexiness with my body. I've been thinking about this for a couple years just I'm still unsure with the pros and cons. If you can tell me anything from experience or if you just know if greatly appreciate it.
