I m 16 and I used to wipe hard when I would use the restroom it used to bleed but I haven t had any bleeding in over a year but the other day I thought I had a hemmroid so I decided to look in mirror and I didn t have one but I noticed my external anal sphincter I think is called has a odd shape it s not perfectly round and at the bottom of it It seems to like indent a little bit not the sphincter just below anus it s really hard to explain but it doesn t hurt ive never had anal leakage but the part where it seems to go down has a diff color but it s only relaxed, squeezed it looks normal like a circle but just relaxed not flexing the muscle it looks more like just a line and it s kinda odd shaped at bottom and a little at top of external sphincter it s just so hard to explain but this has got me so stressed out because I want to join marines but I don t want this to cause disqualification at MEPS on medical exam surely this is nothing but I have no idea what to think. Thank you for help.
