i came from arizona to oregon to see my cousins yesterday, and i slept in my oldest cousins room because we're close to the same age.(he's 18 im 17) but we didnt sleep in the same bed. well when i woke up in the morning, it was all fine, i was just thinking and stuff, and then i look over at andrew while he's sleeping, and he has an erection! like i was really grossed out, and idk why! and i didnt see his penis, but i felt like i did. and i dont know what to do, do i tell him that i saw, or will he find out anyways? im so confused and i feel like i did soemthing naughty with him even though we didnt...what do i do?
