I think Toron was mostly basing his remarks off his own experiences with Razira. She's generally a bit boisterous and rough with other members of the party because they're "hardy adventurers" and... throwing a guy across the room to get him out of danger relies more on speed than gentleness.

Also, while he acts suave, he really has no idea what he's talking about. Every romantic entanglement he's had has turned out trying to kill him before it came to the bedroom... and that's happened a surprisingly large number of times.

Several of them are still chasing the party trying to assassinate us...
