Are love scenes in western novels written for mainly men or women or is it undefined?

At the 99 Cent store I found a series of western novels called “The Trailsman”. They are action packed with good plot twists and are a fun read. But there’s something I noticed about them. Each of them contains 2 graphic love scenes taking about about a page and half each, basically porn in text form.

I’ve never seen this before. I always thought this type of writing was only in women’s romance novels.

Who are these love scenes written for? And why? Do men get off on this? Is it for women? Do they get off on it? And who wants to get off while reading a story? I don’t get it. It seems to be a heavy attempt at tittilation, but it doesn’t work on me, I can pretty much skip it. I am curious though as to why the porn-style love scenes are crowbarred into an otherwise action-oriented story. It certainly doesn’t contribute to the actual story, seeing as how that page and a half could be condensed into about 3 sentences. Who enjoys that type of scene in a book?
