Input: Text: my cross country team at my highschool starts practice 2 weeks before school. our first practice is a 7 mile round trip hike. 

now, i've gone commando for many months. this was the first time i had a problem. see, my shorts (to be put bluntly) chaffed my dick all the way up the mountain. 

no problem! it just hurts a little. 

on the way down, i feel a little bit of wetness down there. not the good kind. then i see flecks of blood on my shorts. i hold it together, get home, and take off my shorts

i now have a small flat part on the tip of my tip. i'm pretty sure it won't grow back. i fucked up.

also, the shorts are ruined. blood all over the inside and a good deal on the front.
