Did you actually ask for consent here? Because it sounds like you didn't. And that could be a big reason why Eric felt dirty and wrong afterwards. He could well have felt that a "real man" wouldn't say no to a woman trying to have sex with him, and once there's an audience watching if he'd said no or stopped he would have looked like a prude and been mocked. Did you ever consider this? Or did you just selfishly decide to push past his boundaries for the sake of your sexual liberation?
Just because a man kisses you don't mean he wants to have exhibitionistic sex with you. Just because a man gets aroused doesn't mean he wants to have sex with you at that particular point in time. You need to realise this.
Also, this article actually comes off as very judgemental about "vanilla" people.
I don't work in the sex industry. I'm also demisexual, and I don't identify as a "kinkster". So I guess you'd call me "vanilla" because having sex that's intimate and loving, is important to me.
However, to imply that because of this I'm not open minded? Sis please. My best friend/polyamorous lover is one of the top rated models on Pornhub, and I actually met her through Pornhub.
