Some people only like to look at one gender. There is nothing wrong with these people nor the people who have no preference, but the point of tagging is not to judge, but to filter.
If someone only likes to look at pornographic images of women, most of the time they do not mind if there is a man in there with her. Based on this, searching only for 'female solo' or 'lesbian' will block out a lot of images they may want to see. Adding 'male solo' and 'gay' to your blacklist works well, but there are things that slip through it.
It's easy to tag any pornographic image containing only males as 'gay', but I can see how that would be incorrect or even offensive. After all, just because two men are in the same place or being subjected to something together does not mean they are gay.
Examples:
post #1569359 - this page of the comic is not inherently gay, nor is there only one character in it. If you have 'male solo' and 'gay' in your blacklist, you're still going to get this image, even if you explicitly do not want to see men masturbating anally.
post #314638 - these two gents are alone. There is a shadow of someone who may be female or may have a weird elbow and is apparently about to do something to them, but she's not really there. There are multiple guys in it and they're not doing anything to each other so it is not 'male solo' and it is not 'gay' but it is indeed naught but dicks and someone who does not want to see naught but dicks would want this filtered out.
post #313858 - I'm not a fan of the way these dicks are drawn, but that's not the point. These guys are just enjoying a hot spring - a little too much, maybe, but it's barely even sexual aside from the erections - or semi-erections, I can't tell if they have furry shafts or really long sheaths. Anyway, there are no ladies to be seen and so if ladies are what you want to see, this post is out.
post #175080 is a post I tagged long ago as 'gay', but I am willing to go back to my earlier statement and say that these two are not doing anything to each other and there is no implication that they are willing participants in this endeavor. Still, if you came here to see girls getting nailed or girls just by themselves, you're 'male solo' and 'gay' filters won't let this pass you by.
To deal with this, I recently started tagging the posts above as 'just_guys'. In the opposite situation, I tagged it 'just_girls', as there is again no implication of homosexuality and there are multiple ladies involved.
A mod has decided to remove all these tags and tell me they are 'not valid tags', to which I can offer no relevant explanation. The only think I can say is the actual wording may be a little casual, but I think it sounds better than 'all_female' or 'just_males' or 'same_gender(female)'.
The alternative to this is to expect the person to type in their preferred gender on every single search. This defeats the point of tagging and blacklisting. There is nothing inappropriate about noting that an image only has men in it and it's a benefit for those who do, or do not, want to see such a thing. The only question should be as to the actual wording of the tag, which I leave up to you all.
In the event that anyone feels the need to comment 'don't look at it if you don't like it' or 'it won't hurt you to see it' I respond; duh. Of course it's not going to hurt me and I don't have to look at it, but sometimes you really just don't want to see something or you can't tell from the thumbnail what it is.
We have tags and blacklisting so that everyone can post what they want and people who don't like it don't have to deal with it. I don't like the My Little Pony stuff. It grosses me out and it's everywhere. I have the option to bitch about it until it gets taken away from the people who do like it, leave, or, in this case, blacklist it and almost never have to worry about it.
That is what I am trying to accomplish here. Not to judge anyone, not to have anything taken away from anyone, just to use the system the way it is designed so people can browse without seeing things that will diminish their personal experience.
