90s movie. American couple lives somewhat isolated while drinking and having a lot of sex.
I was 7 and It's one of the first English-speaking movies I ever saw. So this is going to be a bit messy/foggy
I don't think this movie was military related, but there is a couple or person that often has company living a bit isolated, in what seems to be a bit like a military base (possibly dirt road) and small house by American standards I think. The couple drink glass bottles of beer a lot and lay relaxed on the hood of the car multiple times in this movie. I think there were at least 5 sex scenes. The car is always parked not in front or back, but next to the house, which does not have a garage I think. I think the car is red.
The "neighborhood" looks a bit like this but with much more space. You have to take away at least 50% of the houses for it to be kind of similar. https://www.flickr.com/photos/europedistrict/3986776066
Normally I would put stuff like this on the TOMT section on Reddit to get much more eyeballs, but there is a problem there now.
