Right after I turned 15 I started sleeping naked. Not just because it felt better, but also because it was easier to masturbate at night or in the morning. All I have to do it roll out of bed and I can cum before getting dressed.
Just last night, I woke up in the middle of the night horny and hard. I reached down with my foot and grabbed a sock off the floor with my toes, slid it on and started stroking. I didn't even have to take off the covers to play with myself, and I had an orgasm while staying nice and warm. After I came I squeezed all the cum out of my penis, threw the wet sock back into the dirty clothes, rolled over and fell back asleep happy.
