problems performing with one bud but not with others...any ideas?

It sounds like he doesn't really turn you on, or you two are already too intimate on other levels, or you are too comfortable with him.... I can only think that's it's got something to do with your psyche. Is he aware that you are having a hard time being hard with him? Or is it just you? Is he putting pressure on you? In what way? What are his demands, if any? Maybe you two should just be friends to hang out and do other stuff? Maybe you could find other ways of pleasing him that don't involve you being hard and topping him (fingering, using a sex toy, rimming...?). Maybe this is only momentary anyway. Have you been doing certain drugs recently, or taking medication? Have you been trying to do it after having exerted yourself too much with someone else before?
Do you find this man attractive? Since you are already getting sex from other sources, what is it that you want out of this sex relationship? Is there anything you do with him that you don't do with your other partners, like drink before you start? Lastly, do you smoke?
