People listen to music without dancing, it's the same thing - it activates pleasurable parts of your brain which trigger various biochemical responces. I normally work with video essays on in the background but when things get complex and stressful I switch to hot people dancing or similar, trying to juggle a dozen variables and get all the code loops right can be mentally taxing so when my brain in churning over my options it can be good to have a nice juicy butt to rest my eyes on, watch sway and pop and grind... It's not going to interrupt my train of thought but it holds it.

Also something that no one seems to consider possible but there are some really interesting and funny women that enjoy showing off their body, the music is often great and the atmosphere fun and light hearted - the notion that because it's sexy it can only be low tier, base and worthless is just puritan nonsense, it's good content.

And no you don't have to jerk off the second you see a sexy butt, I think that way of thinking might be more puritan baggage. You can just feel good about seeing sexy bodies gyrate.
