You can have a hard time around your horny friends OR you make the best out of it.
Of course, it is first a bit akward to be the only one in your friend group who actually lost their balls and won't be able to penetrate a girl, but soon you remember what type of horny guys they are.
So yuo play and tease them, and while a bulge forms in their pants, you remain smooth and free from such lower bodily reactions.
Actually, you kinda make fun of their reaction towards you.
