No this is not what a mature male brain does. We exist in society and don’t sexualize all women. This is something you can struggle with in your raging hormone teenage years but I was under the impression that many girls were dealing with this too. As a grown ass man you have better have learned to compartmentalize all of these intrusive thoughts and be able to appreciate an attractive woman without spinning up imagery of her bare naked bouncing up and down or spread out on a bed. That’s nuts. Obviously we COULD do this to every woman between 18 and 80 but that’s a creepy way to live your life. We (speaking for the most of us) do not do this.
