98% bottom. I wouldn't rule it out entirely, but you're going to be waiting a long while.
Ah, that's a good question, pondering the actual character. There's three layers: 1. How he sees himself. 2. What he actually is. 3. What the hypnosis makes him. He sees himself as 90% top, way too cool to bottom unless he was doing someone a favor. In reality, he's probably closer to 70 sub, 30 dom (That smugness isn't ALL self-delusion). But the hypnosis switches off that 30 (and massively amplifies the 70), making him 100% long-eared sex toy.
