Thank you to those who responded to the survey!
As I more or less expected, there were mixed responses, but the majority favored NOT including transsexual content on this Tumblr. One response even mentioned that the exclusively male content is why they seek out this blog over other sites, which I do appreciate.
One respondent suggested that I could create a second blog specifically for transsexual selfsuck content. I had never considered this option, but it actually sounds like a decent idea, provided I can find enough content (as it is somewhat harder to find than normal male content for obvious reasons). I’ll post a link if I do end up deciding to start a second blog.
