Wow, somebody likes to do searched for really old threads.
Just as an update, I've been using astroglide exclusively since the first time I tried it. Oh, and the gf referred to in the original post is now known as ex-gf. I haven't talked to her in over half a year. Turns out she wasn't nearly as into me as I was into her. I have, however found someone much better for me and am quite happy with her.
P.S.- My penis is still nicknamed Bob.
