Yes it was, well spotted.
First up, I have a penis too, and you'll forgive me for being just a little bit sceptical of someone who's been watching online sex work for years and claims to receive absolutely no sexual gratification from it - but that's neither here nor there anyway, it doesn't much matter whether the interest or entertainment value you get from it is sexual or anything else, it's still something you're getting entirely thanks to the efforts of other people. And the 'browsing in a shop' analogy doesn't work at all, because it's a show - to browse a show for any period of time is a concept indistinguishable from actually watching it.
Do what you like, of course, all of us here are aware that guests and lurkers outnumber tipping members and that's the way it is. But don't kid yourself about what you're doing. And as
@swagger observed, on a site run by and for women who perform these shows, and who in turn rely on other people to be willing to pay something to make them happen, you're unlikely to get a positive reaction for cheerfully admitting you've been contributing nothing to them for all this time.
