Our body naturally produces a small amount of fluid when healing; this is plasma. When it dries it will leave crust around the pierced area, along with some localised swelling. This is NOT an infection and is just the body trying to deal with a foreign object and all part of the healing process.
Unfortunately it’s very tempting to pick the crust (we’re all guilty of it), but you must try and leave it alone as much as possible, especially with grubby fingers.
By the way, having a particular piercing on a particular side of your body does not make you gay, a common and bizarre misconception. Believe it or not, we do get asked this – more often than you’d think!
