fuck off. it's one of the fastest growing niches in the porn industry right now.
I agree. Make one for "straight men" and one for "gay men". The problem is a lot of guys don't identify as "gay" on their profiles. They will just put themselves down as "male" or "man" as we are so used to doing on other surveys and forms. But adding a sexuality filter would help with this. You can both be a "man" and a "gay" and these two filters would help narrow down and solve the problems that you are suggesting. No more gay ads targeted towards straight male users.
So in summary, maybe having another identifier would be extremely beneficial.
Then instead of just searching "male" and not knowing who will get angry at you if you try to add them, you could be more specific and checkbox a list of identifiers like "gay", "male", "top". Or "straight", "male", "dom".
Gender, Sexuality, and sexual position or kink (last one is not necessary but a personal favorite). Those options can also be added when uploading videos to avoid mixing these two categories together and upsetting users.
