Unfortunately it takes a very long time to heal. I won't tell you how long mine took so I don't depress you, but mine was very, very long. Hopefully yours won't be long. You do get used to it, and you can be confident it will eventually heal, so hang in there.
The reason it takes so long is that the skin has to granulate. If you think of a slice wound on your finger, if you can keep the sides together (like with a bandage or even a stitch), then the edges that touch rapidly grow together. If they are not touching and there is a valley in between, then lots of new skin needs to fill in (that is granulation), and that takes time. The nature of this area is that sitting, walking, etc. keep pulling things apart, so you end up with lots of granulation needed. It's also an area that gets warm, so there can be some dampness from sweating. I never had an issue from infection, so I doubt that is a concern, even if it is wet, yellowish or red.
The thing that really helps it is packing it. That means taking a strip of gauze (look for packing gauze) or rip strips from a pad, and pack it in as tightly as you can. This absorbs moisture, helps granulation by keeping new skin from re-opening, and generally makes it feel better. Pack it as tightly as you can and if it gets damp, change it often. Expect it to get yellow or occasionally red. That's not a problem.
Just give it time, don't fret, and good luck.
