Any idea if Popper is better listened during sex or prior, considering the short-lived effect?

While Excite is a nice dose, it is kind of impractical for what it is intended for to listen 50mins.
Something with same effect but much, much shorter would be great.
In general, most of sexual doses would be good in QH format.

I wonder if someone could explain to me the purpose of visualisations in I-Doser premium application?
As far as I understand it, doses are supposed to be consumed with closed eyes and watching the visualisations just presumes eyes being open... Kind of confusing.
