Of course Ian is quite capable of being a stud himself, just not on the cuck route. On the cuck route, Lena was always a slut, even when she pretended to herself and others that she wasn't. I mean come on, she's fucking Robert the whole time, a guy she doesn't even really like. Only a slut would do that. You see if you play the cuck route, the way it should be, Ian never has sex with anyone else but Lena. He's completely obsessed with her, and has her on a pedestal. And all along she's just the opposite of what he believes her to be. She really is the party girl that Jeremy claims. Definitely not girlfriend material, unless you're really a cuck of course.
Everyone in the game thinks Axel is a stud. Even Emma and Alison are positively drooling at the sight of him. And Jeremy who views himself as a stud, is intimidated when he first meets Axel. The famous fashion designer, who turns up at Seymour's second photo shoot, and is probably feted by loads of hot male models, even views him as the Greek God Apollo, because of his perfect physique and overwhelming manliness. Honestly, I think you must be playing a different game to me.
Lena, still thinks Axel was the best fuck she ever had. She hates him, but even so she can't deny that. Whatever route you're on, she's always going to like Ian, and he has the potential to make a connection to her, that Axel never could. But Axel can also fuck her, like nobody else can. Because he can dominate her completely, and deep down Lena wants to be dominated by a man. But Axel's problem is that he can't commit to one person, but he expects the person he's with, to commit totally to him. That's why ultimately he's going to fail with Lena, whatever incarnation she takes. If she's a slut, she'll want her freedom. If she commits to him again, he'll cheat on her with someone else. It's a no win scenario for Lena, unless she just treats Axel as an occasional fuck.
