Slept with briefs on until I got married. Wife (at the time) slept naked and convinced me to do that (30 years ago)...and being doing it every since. I slept naked even with 3 daughters around but wife went to nighties after they were born.
My boyfriend and I sleep naked all the time now. It's awesome. He wakes up before me, he's horny, flips me over and has his way with me--no clothes to interfere and it feels wonderful. We're both cut and gay.
