What are the safest/hardiest piercings you can get?

I want to get new piercings but I can't make a decision on what piercing would be best.

I've had no luck with eyebrow piercings- got them done twice and both times they didn't want to heal, got infected and rejected (one within 6 months and the one I'm still fighting for is at 8 months). No luck with a nipple piercing either- basically the same story - in a year and a half I had it, it never healed and kept getting infected.

I've got several generic earlobe piercings, ear gauge, gauged septum and probably more penith piercings than necessary. None of these piercings gave me any issues besides flare ups while stretching

Does anyone have any recommendations for a fool proof stab?

(Edit: piercing placement wording)
