Let him know upfront
Met my roomie for the next 8 nights today. A Canadian about 10 yrs older than me. We got back to our room just in time to crash. He warned me he pees frequently during the night. I told him " I sleep naked or I don't sleep". As I shucked off my shorts. He said " fine with me I will get there"
Want to share my experience. I had gone to head office with my colleague to attend a seminar. Both of us had to share same room in the guest house. After work hours we had dinner and returned to the room. My colleague changed to his night suit and slipped in his bed while I just walked around in the room thinking something. My friend sensing my confusion asked what is the problem. I quickly told him that I have habit to sleep naked. To my happiness he replied he had no problem about it. I spent no time and quickly took off all clothes and happily jumped in my bed naked.
Lol. I sleep naked and pee several times during the night.I hope you get out of bed before you do. LOL!!!!Nope he does not... So he wrote a book about it. " Rusty Bedsprings " by I. P. Nightly
Actually I do get out of bed for my several pees each night. So others may well see me naked. I have been caught by my late wife's friends on my way to the toilet.
