No, it isn't. Ace and Twigget both noted that their male personas were gradually being submerged by their new female personas; including in the strip I linked to.
That's why Brooke said she was keeping an eye on Kade, to keep him from doing anything he might regret later. And in that same strip, she likened it to her own experience when she was changed by the orb. And while they wre at the park, Ace told Kade he forgot to warn him about the hormonal effects of being a girl (panels 2 and 5).
Ace fought it up until the very end, Kade didn't. But both were being affected by their new physiology which was gradually causing them to think and behave differently than what was normal for them.
Again, compulsion takes many forms.
To a human, the thought of consuming blood is disgusting. For a vampire, blood is not only essential for their survival, they can derive different flavors from it, and the victim's blood can even be addicting (like Chloe's), or tempting (i.e. Faith's).
Teddy is currently part succubus/part reaper (whatever that entails). For a normal human, sex feels great. For a succubus, it's quite literally what they live for. Lucretia even said her body was (quote): "built for sex".
So we're clear: I'm not arguing that Teddy is definitely under some form of compulsion. But if the writers were to reveal that he is, they've at least given themselves leeway for it.
