I agree with being yourself. That's how I found my wife and we've been married 7 years now, happily. We're two guro loving transgender freaks working in the sciences and we would have never found each other if we hadn't been honest about ourselves from the get go.
You can get her by putting on a mask, but eventually she will learn who you really are and that more often than not end with disastrous results.

Ask her on a date. A real date. If she says no, brush yourself off and soldier on! As long as you are confident and brave enough to approach women, you will find your special someone in time.
