Me and my gf both are into doggy pose, and it's usually comfy regardless of our height difference. However, there is a black rounded bulge covered in the middle of her anus opening, and sometimes protruded with spreading the cheek. I asked her about it; she said it's a hemorrhoid for two years, but she didn't feel it on a daily basis including sex.
I used to only apply some slapping and massaging of butt cheek, and she responded positively about it. Recently once in the pose, I asked her permission and softly place a thumb with saliva to rub her arse. I asked her feelings during rubbing and she told me it was a bit itchy and comfy; so later with saliva, I slid an index very slowly inside about 1-2 knuckles. This got her moans, and she told me after it was an intensified experience.
Not sure why, but the finger was actually all right with little smell to be washed off, and the knuckle appeared as clean as the rest after pulled out. Frankly speaking, it was a rounded soft tissue in the opening to block enter, but after fingertip passed, then it was empty inside.
In recent times, I trimmed nails with lube and she's good with one of other digits as well other than the thumb (got the hemorrhoid squeezed in).
The problem though, was the hemorrhoid as well as the surrounding muscles seemed to turn outward from behind with finger after some while. Another problem was farting which happened sometimes after the hemorrhoid turned outward, and the finger tended to get a bit deeper with farts. She told me once a looser and defecating desire afterwards when she went to the toilet, but nothing was there.
TLDR: I'm curious if the hemorrhoid should be worried if the finger can avoid and surpass it. No toys, but a finger or maybe two.
