Weakening? Maybe.
I process holistically.
So while I'm having sex, my mind is adding up my household bills, remembering hot scenes from movies, going back over the last 10 or so really good partners I had, rehearsing how the fuck I'm going to leave afterward without being rude. I'm also distracted by my stupid garters, wishing I'd got the sticky kind, hoping he doesn't want it doggie style bc I FUCKING HATE THAT POSITION!! hoping my kid's ok bc he's halfway across town with my miserable sister who can absolutely not under any circumstances know that I'm having sex. Ever. Thinking about the last book I read and the last song I listened to before I came over.
Sometimes I'll visualize dreamscapes that are purely imagined.
And all this goes through my head in under 10 seconds. Forcing myself to focus on bottom-up reasoning is what gives me a headache. It's like trying to use a boomerang as a spear.
So yeah, hyperfocussing on somebody else's sexual fantasy is like work. I don't do it for just anybody. Again, it's easier to shut all that thought-babble off if I just shut it ALL off and focus on the sensation.
