I'm 28 years old and typically gifted when it comes to lovemaking. I know how to touch a woman, pleasure her and I know bedroom inside and out. However there have been times when my lovemaking was less than stellar to say the least... Just this Thursday I visited my girlfriend at her dorm. We had incredible morning sex and she claims to have orgasmed more times than ever. Our escapedes went on for more than 2 hours that day, not counting foreplay. In our 14 month relationship we both agree that this was the best sex we ever had. That brings us to the events of last night and this morning. I just couldn't get my head in the game. I would get hard and then it would go away. Get hard, go limp. We tried to have sex 3 times. 0 for 3. I went limp each time. Twice while I was inside of her. My mind was racing and I couldn't focus on the task at had to save my life, and after my first failure I became self-conscious and failed again because I was trying to force the issue. My girl is awesome, she says that it was okay and that she wasn't disappointed, but I was. My question, how do I keep this from happening again? I know I don't have ED, but when my mind starts to wander and I lose confidence I'm useless. I consider myself to be great in bed, and I've never had any complaints, but this is becoming embarrassing... Fellas, has this happened to you? How do you keep yourselves focused?
