Is this pilo?

What do you think?
Yesterday i found blood on my underwear, but it was dot shaped and a lot lower then the hole.
Also i have been exercising and i always sweat a lot in my butt crack to the point of leaving e wet stripe on my underwear which i don't think is pus because only appears after i sweat a lot.
Pressing on it doesn't hurt.
No lumps that i can see or feel, no pain at all sitting on it, it doesn't bother me but i want to know if i need to get this checked out.
