I am a 15 year old male, that has been having problems with excretion. I can not poop easily and many times, in order for me to poop I need to use the help of my hand to remove the feces. This is my fault since when I was a kid, I wouldn't go to the toilet on a regular basis. I would never poop in public even if needed, so I learned to bypass the urge. I could go 3 to 4 days without pooping. I believe I have developed hemorrhoids and I can feel different parts in my anus, not like when I was small and could poop normally. When I was small I would excrete feces that would be freakishly long and thick. I have been using my hand for 2 to 3 years. I do not always use it, but most of the times I do. I have for quite a few months, abnormal burps an I have to force myself to burp. Whenever I do though, they are very acidic. At times I get some acidic liquid up my throat as well. And if a lot of time (6h more) passes without me releasing any sort of gas, I have to release gas and at that point, it just releases via burping. Recently I have also lost the desire to eat in general. I feel full and I do not seem to be producing feces or I do not excrete them? I had eaten normally the previous days, and had not pooped, so I expected that I would poop a lot when I went to the toilet, but nearly nothing came out even though I used my hand, and it felt painful and weird compared to other times, it felt like the feces was stuck in between holes or spaces? I even used a pill, similar to an enema, but there was only liquid coming out afterwards. I also have difficulty in releasing gases via the anus. I do not exercise nearly at all, but I eat a lot of vegetables and fruits. Around each day I eat a large salad. I do not eat a lot of meat and nearly no fried food, but I eat a lot of legumes. I always put a lot of olive oil in my diet and I get I believe a decent amount of fibre yet my anus is always hard, like not lubricated by the fibres. Please help me cause I honestly do not know what to do.
