Re: Erection issues again.
First of all, how turned on are you when you are about to have sex?
I've had the same problem as you and I've found that the only time my erections are good is - surprise - when I'm actually turned on. You can't be worried about things, particularly losing your erection, and still be turned on at the same time (and thus have an erection to show for it).
The best thing to do is only have sex when you are really horny. That way you are pretty much dying to get off and won't be too worried about losing your erection. It works for me.
