Women definitely do that kind of stuff too. I've had several girls tell me stories about guys talking a huge game and then being extremely underwhelming (cumming in minutes, average size after having claimed to be big, etc...).

If you think about it, when women wear padded bras, spanx, etc...it's kind of the same thing. In a way it's worse because with the sex there was a chance she could've been fine (at least in her mind), whereas with the deceptive clothing they should know you'll find out eventually but they still do it.

In this case if I'd suspected she was trying to emasculate me, I would've been much, much less forgiving. But I'm pretty sure she was just insecure and trying to talk herself up. Also I think she just wanted to try a big dick but didn't want to appear to not know what she was doing.

Most of us are insecure about one thing or another. It's just a question of how you deal with it and how deceptive you choose to be with people around you.
