First, I want to say that I am a long-time Cock Hero fan. I very much appreciate all the effort that goes into making these videos, especially considering that none of you dudes get any compensation for doing so. If I had the time to make these videos (I have a VERY busy career, a live-in girlfriend, etc.), I definitely would. I still try to offer my support in any way I can, usually by seeding as many Cock Hero torrents as possible. So I want you all to keep in mind that when I make the following suggestions, I'm not trying to be an ass, and hopefully there are others who can sign on to what I'm about to say.
Although Cock Hero is a great idea, I find myself genuinely enjoying fewer than half of all the videos. I think the future of Cock Hero should be the creation of more challenging videos with fewer breaks, and I voted accordingly. Also, my favorite videos and the ones I find most challenging are the ones that have a greater degree of interactivity and/or story. I liked the Self-Control videos a lot, the video game theme of the Stroker Ace series, and I think we really need to bring back text-based teasing like in the original Cock Hero series. Maybe I'm alone in this, but I think that Cock Hero should immerse the viewer completely, and this isn't as effective if there's nothing to the video except for "here's videos of hot girls getting fucked and some beats, have at it!"
The biggest issue for me is that many of the videos lack variation in tempo and intensity. Some videos are all speed while others are all midpaced. Both tend to get boring very quick. Maybe it's because I've developed exceptionally good orgasm control over the years (I have actual sex far more often than I masturbate), but I find myself going soft, getting bored, and fast-forwarding through videos that have this issue. Less often, the issue is the content. I realize I'm not the majority here, but generally speaking I am not in the least bit turned on by women with fake breasts or who look too much like traditional "porn stars," or women who have outrageously disproportionate features in general. That's why supermokkori is my favorite Cock Hero editor. Girls like Riley Reid and Mia Malkova make me weak in the knees. Blow-up dolls like Aletta Ocean literally do nothing for me.
TL;DR: More challenging, more variation in beats, fewer/no breaks, more complex/involved stories, and fewer chicks with fake breasts.
