This is a question (the OP's) that always puzzles me: you don't have to play those games. You don't have to play them at all. There's at least some merit to asking why there aren't MORE porn games with male protagonists out there, even if it would be a little silly to, since most games that have been developed and are still under development have male protagonists. I think what we're seeing now is more developers who want female protagonists and more people who want to support them. That's great. At least some of those people wouldn't make a game with a male protagonist in the first place, so this probably means more people want to make games. More games, in my opinion, is generally good.
If you want something else, support the devs who are making things closer to what you like. Tell them they're doing a good job, financially support them if you like, maybe even start making such a game if you have the interest and skill and think there's a market for what you'd make. But don't come crying to people who like different stuff that everybody should be making games for you and only you specifically. Other people have their own needs. You are not the center of the universe.
And just for good measure, this goes for the people who like female protagonists too. No, not everybody needs to make a game with a female protagonist now. Some people are, and I'm happy for you for that, but I'm never going to tell somebody that they need to stop making a game with a male protagonist and make the protagonist female just because some people don't want to play a game with a male protagonist. I like playing porn games that star dudes. That's my preference. And as long as there are people out there making games you like, telling people to stop making games I like so they can cater only to you instead just makes you an asshole.
