I too have Netflix.
This movie is rated R and has a Common Sense rating of Iffy for 17+
The very first review says, “there is some (hetero and homo) sexual content, and there is a healthy dose of (male and female) nudity.”
Sounds to me like you didn’t take the time to read the information that was provided. I don’t like watching dudes swap spit either but I take some personal responsibility when it comes to selecting what I watch.
You are right. I didn't read anything except the description:
Thinking they've cooked up the perfect crime, Vic (Eddie Marsan) and Danny (Martin Compston) abduct young heiress Alice Creed (Gemma Arterton), only to find their surefire plan unraveling as they attempt to negotiate a tidy ransom in director J Blakeson's twisty thriller. As the steely Alice lies tethered to a bed, an escalating battle of wills -- and wits -- ensues when setbacks shift the balance of power.

I see now that in genre it's listed as gay lesbian. It's not Netflix's fault, but my own. Up to this point I had never encountered anything like this so I really didn't know that the description given was not enough to know what the movie contained. I am enlightened.
I pulled up the Netflix title page, as I just finished watching something else.
At the bottom of the title page, just below the length / date / R rating is: GAY & LESBIAN MOVIES - THRILLERS
It would seem that adding an H rating would be repetitious.
