In all honesty, when I first found cam sites, I was like a lot of the freeloaders who just didn't want to pay for nudity/porn because "why should I, I can use google and get shit for free".
At this very same time, I would see guys chatting in the public chat and I would constantly be thinking "wow, what sad losers they are... just stfu and masturbate already".
I wish I could say that this was when I was younger (my early 20s or something) but sadly it was not (late 20s). My mindset was like that, I think, just because I had grown up around the internet and accessing "free porn".
But the more I watched, the more I saw how entertaining and fun it was to both tip and partake in the chat with the models.
It was also the fact that I was able to see REAL women, you know, the kind you would see in the street. It wasn't staged porn with scripts (I know some rooms are "in the office" ones for example), but for the most part, it's just beautiful women.
Since then my mindset has changed completely, and I have learned so much not only about women as models, but also women in general (definitely not claiming to be an expert, even you ladies are no expert on yourself, how can we men be lol).. But it's been a truly fantastic (as weird as that is) experience overall and models/ladies have just helped me see/understand a lot.
Anyway, I started as a freeloader hating and not wanting to tip. I started to tip because I realised it was amazing and fun to be involved, you have so much more fun and honestly, if you do jerk off, it does feel better. Now I tip for the entertainment side still and having fun in all ways that may entail, but also because it's just "nice".. as lame as that may be.
