The users cut/uncut status could be asked in the same form as hair color etc.
It would then be easy to filter out cut or uncut guys depending on your preference, for example using the same dropdown menu that contains "jerk-off", "blowjob" etc. Rarely do people tag their videos as cut/uncut, but most would answer the question once in a similar manner to hair color, height etc. The best system would be the options were uncut / cut at birth / cut later since the circumcision style is often different when cut after birth later in life.
Thank you for your feedback and suggestion.
We will forward this to our team for further review.
Keep the ideas coming as this is the best way for us to improve.
