Confused about the meaning of being Aroused to start a session.

We often see tips/advises like this in the same post :

– Clean the slate. ( Relax , meditate or “Put out of your mind all of the thought processes by which you achieve a traditional penile orgasm.”)

**And**

– Start your Aneros sessions aroused.

What do they mean by aroused in this case ? Sexually or not aroused ?

I don’t know what to do, i traditionally look at photos , porn video, etc… first to be aroused first and after i do my sessions (some time i lets some selected photos (no video, too distracting), that i love to watch , slideshow on TV while lying on Sofa to help with staying “aroused”). that doesn’t “work” for me any way.
