Title pretty much states my question; As I'm into an LTR for a while now, almost a year, I find myself wanting to "open up" to my girlfriend and reveal some insecurities. And other similar things that wouldn't necessarily be "attractive" in a traditional sense, but a sort of relationship thing of being comfortable and open with your partner.

Especially when it comes to something like sex, attraction, desire, and the like, it seems like a hard feat.

Advice?
