Well, I have another question further down to another guy about how he imagines sex, I guess you can answer that as well.
But also, how do you solve math problems? Often the you need to draw a graph and look at some crossing points. For me, I can conjure up a video in my mind similar to 3B1B, and I use that to think about the problem. It can even get complicated enough that it would take me a while to draw on paper. How do you solve such problems?
Not the person you asked, but as someone who also cannot see mental images at all I'm not entirely sure what you mean by "imagines sex". I don't really imagine sex and self-gratification is usually not worth it without visual aids. The times I pull from memory, it's more about the overall experience rather than visualizing anything specific.
As far as math goes, I've always been pretty good at it. I generally don't think about graphs at all in mathematics. That's something I associate with learning math more than I associate it with "doing math". The only time I'm reaching for more complicated math is in a computer science context so I'm rarely trying to solve anything other than arithmetic or rough approximations in my head.
What does memory even mean though, if you cannot recall the video of what happened? I find it hard to fathom you can recall an experience without replaying the sensory impressions you got. It's almost definitional, isn't it? To remember something that happened to you is to be able to re-experience it.
