Maybe I should create an extra thread but I thought asking here might also make sense.
Can someone recommend me a few games where the MC is not displayed as a weak looser? Obviously, this means that the femdom is likely forced upon him. Karlsson's Gambit is the only game which I've played where it is somewhat like that and the MC also has a dominant path which is the cherry on top for me. Thanks in advance.
Depends on what you mean by "weak loser". Do you mean a protagonist that can act cocky and dominant, at least on some paths, in a femdom game? (kinda like the one in KG) And, if so, are you also into it if the point of the game is that that character will get defeated/tamed/enslaved by female characters by the end of the story?
If it's the former I can't honestly think of other good games like that. If it's the latter, I can already recommend MironHFG's "
The Renaissance", which already has some maledom blowjobs scenes and a very cocky protagonist, but keep in mind events outside of his control are almost definitely going to lead to his death/torture/lifelong enslavement (in different endings) and lots of cruel indignities being done to him by a group of powerful and ruthless gynarchist women. (the plot hasn't gotten there yet, but knowing Miron's track record it's only a matter of time...

)
Mistresses of Hell, GreyCrimson's sequel to Mistresses of the forest, also goes for a similar cocky and proud protagonist about to be broken, although I think that game was abandoned.
League of Domination has a maledom path for Lux at least, and you can combine being dominant towards her with being submissive towards any of the other girls if you so desire.
Trials in Tainted Space definitely allows you to be a smart and strong protagonist, but also defeated and forced into femdom scenes by various alien female beings, so, even though I haven't played it in a long time, you might want to look into it.
Oh and, not to forget,
Seeds of Chaos is probably the best fantasy VN I have ever played where you can technically be smart, strong and dominant in some scenes as Rowan, the male protag, submissive and weak as Alexia, the female protag, while Rowan will also be forced to submit to a smarter-than-him and hot female demon, Jezera, (you can choose to submit to her twin brother as well, but I'd assume you aren't gay and wouldn't do that given your post here...

) and potentially hypnotised into submission by my favourite character in that game, a millenia old female mage named Cliohna. (you can also resist her and play a defiant and strong-willed Rowan against her, but I have no idea how that path goes myself...) There are a couple more female characters you can submit to, as well as others (which I was never very interested in myself) that will mostly submit to Rowan.
Anyway, obviously I'm not into maledom so I don't play Karlsson's gambit as a K5 or higher, nor did I play Seeds of Chaos as a dominant Rowan, but you can and you will still experience some femdom in both games if you do. It's still probably best to start a thread for this, as it's a pretty specific fetish which most of us here won't have...
