Speaking of interesting confessions, Beau, my boyfriend and I are both big Star Trek fans too! We have phasers and I have a model ship, but he has schematics books, and a box of old Star Trek magazines. So he wins that battle. But wait, I have action figures... Hmm...
There are tons of other nerdy things that we both like, but meh. We are just two big dorks!
To the person who posted after me, green stuff, whose boyfriend is a Star Wars fan too, that's so awesome. It sounds like you two have fun with each other's hobbies/borderline obsessions.
