My boyfriend and I (gay couple) have been together for over a year now. Since we've been having sex we've noticed that he always has a rip in his anus afterwards. We originally assumed that it was a recurring rip, since it would only cause him pain for about a day after each encounter, but recently it has occurred to me that this is likely a single ongoing fissure.
So with that realization, we've refrained from having sex for about five weeks now, and I've been putting Neosporin on the fissure daily. Still, it doesn't appear to be getting much better, if at all. The rip is on the top of his anus (opposite his perineum), not far from the surface, and it is about 1/4" long and almost as wide. It doesn't bleed or cause him discomfort, but it is clearly a fissure, and I'm afraid that it will only get worse if we don't get it to heal soon.
Also in the last five weeks, I've been encouraging him to eat more fiber and to soak or gently wash the area. I'm beginning to wonder if perhaps I should stop putting Neosporin on the fissure, so as to refrain from opening the wound? I would suggest that he visit a doctor but my understanding is that there's not much more a doctor could do except perform surgery on his rectal muscles, which is an idea I am not fond of.
Is it unusual that a fissure lasts this long with no apparent signs of healing? Is it unusual that a chronic fissure would not cause pain or bleeding? Is there anything else we can do to aid his recovery?
