Any Other Guys Ever Lost Their Sex Drive?

Yes, I lost my mojo.

Lately I have become totally disinterested in sex, which is particuarly odd, as I have just begun courting a very very attractive young lady. But all I am really interested in is befriending her, getting to know her, letting her know how I am, and reaching that stage where we are comfortable in eachothers presence, and can just hang, or call eachother up to talk, or go for long drives in the middle of the night. I am early 20s, in a high stress job, made worse by the fact that I worry, and stress alot anyway. Apart from that, life is pretty great (and I still like my job).

As this ever happened to you? Have I peaked, and it's over? Mabey I just have to many other things to think about, and adding a relationship to it all, ment I didn't have time to ponder sex for 20% of my day anymore?
