sex combat at these stage is not really against enemy's it is mainly against some party members and so its more for sake of sparing or some dumb competitions rather then fights with real stakes. so these attacks don't make much sense in context.Well, if you're going to have combat in a sex game, and you go out of your way to exclude the most effective and fundamental attack against a man(both physically and psychologically), it comes off as unrealistic(especially if you're fighting women, who are universally taught to go for the balls in any fight). I get not wanting to feature this kind of sexual attack in a PG rated game but, in an adult rated game, there's no need to try to sensor around it and it should happen way more often.
I'm not telling you what to put in your game. You do whatever you want. That's just my opinion though.
main logic is like "existence of casual sex means competitive sex should also exist "
