Ive had a rash on my rectum and around there for 6 months straight, what does it look like?

Since maybe October i've had a consistent itch on my bum. Maybe only one week since October did it not itch. It's MUCH worse at night. I rarely get the urge to it h during the day. It also doesnt hurt or anything. I dont have any other symptomns. However if i itch too hard i do bleed there. Only really happens after cleaning up after a poop. I managed to take some photos today and it looks like a little weird. Like a strange rash. I itched the darker red spots and they started bleeding. But generally the whole area is light red. Thanks Photos are attached below, obviously Not Safe for Work:
