Actually things get heated up - like really explicit! The movie doesn't hide it (imdb is also telling you what this will be showing - a lot) - there have been a lot of surprises watching movies for me, different sorts of surprises. Because I mostly don't read up on what I'm about to watch. It's supposed to be a fresh experience for me. The movie starts with intercourse though and yes you can see everything. So right off the bat (that's not an innuendo is it?), things start ... coming together.
Now you could ask, is it necessary to show genitalia? The story would have worked with less for sure, though there are some "shocking" (for some gay sex is probably even more than just shocking) scenes that are probably elevated by it. It also would be like asking if a horror movie had to show all that blood and gore. There are different movies for different tastes. And yes this is a drama about relationship, commitment and the "forbidden fruit" (relationship) ... sort of igniting a fire that got almost extinguished.
There are different layers to this and if you don't mind the sexual nature of it all, the story is quite decent. Acting is ok too, even if not top notch. Since you've been reading what this is about your a couple steps ahead of me - no pun intended - in your decision making process.
