what you are describing is very common, and should happen, as it shows your body is connected to the brain and emotions. when i used to go out with girls, i had this gf who made me horny all the time. we would fuck everywhere; in the uni toilets; in a churchyard, in front of one of my friends, etc. When we broke up i was devastated and thought: I need a new girlfriend NOW! So, I persuaded this girl I thought I fancied to sleep with me. result? nothing! I just wasn't really into it. MOre recently, when I've felt depressed or stressed, I find the same thing. Zero reaction in my pants to external stimulation....
