group of friends get together at a cottage or house (not horror). Might all be male, but not positive about that.

one of the friends is gay. one of the friends talks a lot about his girlfriend is and how hot they look together.

bedtime scene where the gay friend and the other friend have to share a bed.  The gay friend starts touching the other friend while he is asleep and I think they might start kissing.

I think there was another scene of the other friends hearing the two getting it on and commenting about it.

Movie is in English.  Watched in the last 10-15 years maybe.
