If you're replacing an existing professional skill, whether from the normal chargen or my bonuses, she can use it. Of course, in that case you'd also have the points that you had added to the previous skill.<br/><br/>If it's a new skill, yes, you do need to find a teacher before using it. It can be a book, too. Until then, she could be subjected to such a skill, but not use it herself.<br/>Of course, you can always roleplay such an attempt. It's just that the skill would make it much more likely for the attempt to get you anything. (Anything but sex with an willing subject, that is :P).<br/><br/>Either way, finding a teacher/manual is THE way to raise skills under my houserules. The other ways are to get a fumble/fumble your resist roll, or to teach it to students.
