[2] Most gay bathhouses, bookstores, and bars in the United States do not openly advertise their actual sex-on-premises purpose or activity, as SOPVs elsewhere can.
[citation needed] "Backrooms" consisting of small cubicles with expensive-to-view video machines are usually attached to an adult bookstore.
"Backrooms" of pubs or bars are usually darkened rooms with or without continuous (and free) pornographic films, but without any dividers or privacy, encouraging group sex.
Club style SOPVs are an entire venue [citation needed] and often consist of small cubicles, sometimes with no bed or mattress, unlike gay bathhouses which usually have some kind of comfort amenities in individual rooms.
Sometimes special events are held at pubs or bars that include sexual activity without causing the venue to be classified as an SOPV.
