Despite the words the op used, it is indeed getting harder to find rooms on cb and mfc, where the girl does not use either lovense or ohmibod. It's just that the majority of the guys love it, so girls use it too (me too). Vicious circle for members, who don't like it. It has indeed changed most rooms at the sites and it happened over a quite short period of time.
Sure, guys can always take a girl private, but not everyone can afford a private. Tipping in public for something you don't enjoy seeing is something that cannot be expected from users in my opinion but the alternative rooms without lovense or ohmibod are indeed getting fewer and fewer. So the alternative for these guys might really be to leave cb and mfc in the end.
