Complications after first time anal sex

[tarack]

Hi. I really need some help . To get to the point I am a 27 year old male. I was under the influence and had unprotected anal sex for the first time ever three months ago. I cant believe we were so stupid about how carelessly this happened and I regret it with all my being now. It was rough and it hurt so we had to stop. I do not think my anus has fully recovered. It has not felt the same since as I have had on and off pains and discomfort in that general area since; mild internal pain every now and then for day or two at a time. Fastforward to now my anus gets sore on one side or the other everyday. No itching at all ever. During this time I kept checking for visual signs and some days the anus ring would just look inflamed and somedays i was just experiencing discomfort inside, somedays it was just sore in areas. As of now It hurts and looks like when your skin gets damaged by friction. A week ago that wasnt the case - but this is it in its full form. I cannot figure out what it is, hemorrhoids / fissures / herpes / an STD I cannot tell - and it just refuses to completely heal - there are days when i barely feel any issue but then it starts all over again. For some reason i also have a hunch that it gets aggravated by my working out. I am extremely embarrassed of this - i live in an extremely conservative part of the world culturally and religiously so going to the doctor and dealing with it is going to be a very difficult situation for me. If only someone can give me any idea as to what it could be it'd be immensely helpful. I cannot explain the stress and discomfort this is causing me.
I have attached pictures below (view at your own discretion).

It could be one or more of several things. You could have gotten a tear, or several tears. These are hard to heal in this area because they can become irritated every time we have a bowel movement. You could also have hemorrhoids. They do not always cause itching.
Even though it would be embarrassing to you, I highly recommend you see a Dr to find out what's going on. Believe me, Drs have seen and heard everything.
If you do have a tear that's not healing a Dr can take care of that. If it's hemorrhoids then the Dr can tell you that's what's going on and recommend a medication.
