So, i've noticed on and off that the inside of my anus has been hurting. i think it might be from having sex. Theres no bleeding, no apparent or obvious lumps or bumps, it doesn't hurt when i go to the bathroom, but it just hurts when i sit for long periods of time. if i had to explain what it felt like, i'd have to say like sitting on a bruise. I'm just kind of scared to talk about this to anyone in my family, so i wonder if this is something i should be concerned about.
