as a married woman who is not too opposed to pornography, i'd have to say she's trying to get you to fulfill her fantasies. sure, maybe this military guy does turn her on, but you should feel great and relieved that she is talking to you about taking a self-defense class and becoming more like this other guy. if she wasn't wanting you to fulfill her fantasies, then she wouldn't be talking to you about taking a class because she'd just go for the other guy.

basically, what Webgoji and Odee said, lol.
