The Timid, wich is not the introverted, hardly seduces
He is waiting, waiting and still waiting for something to happen, that magically, the woman who interests him notices him(no one know how) and come forward to him.
Unfortunately it never happens, only in rare special cases when his air of not caring at all and stand aside can be exchanged for mistery, but only by the most inexperienced/naive and less secure girls.
The other ones can at a glance to understand the difference(even a mile away) and almost never come close to such person.
Even it happens particularly in adolescence that they are also subject of mockery by some couples of witches enjoying themselves to make fun with them that are weaker.
