How horny are you when starting a session?

I'm having a difficult time getting turned on during an aneros section.

Normally, porn or imagining something hot instantly gets me hard. However, I find it difficult to get sexually excited during aneros sessions. Porn doesn't excite me, and it's hard to focus on something sexy when I'm trying to focus on my breathing and contracting.

I'm just wondering how horny you guys are when starting a session, or if it just involuntarily happens as a result of the aneros being inside you.
