Three Men, One Bed

I met three guys.  I asked which was a couple..an unofficial spokesperson for the group ..quickly  responded that they,all three, were a couple..

I asked about the sleeping situation..wondering if each man had their own room..I was promptly
corrected by the spokesman..he clarified that all three of them shared one bed ..

I was stunned by their status report.." what if a person grinds their teeth or snores"? I questioned

Not a problem, I was assured..

Is this a direction a relationship can have when all is comfortable in their own skin?
