Erection Trouble 101

[sera300]

Have you spoke to your primary care physician? This is a topic you can read about here or discuss with your MD; which I do suggest.

Nerves can do it to you and knowing you are having sex with a person present changes the dynamics. If it's not an issue solo, practice or masturbate prior to having sex.

I have not spoken to a primary care physician yet. I might have to look into that one.

As for not being an issue solo, it is. As stated in my previous post, no matter if I'm having sex, or masturbating my penis is ultra sensitive. I've tried masturbating beforehand, and it's helped with sex, but only slightly. I have a lot harder time getting an erection, and when I do I can last maybe a minute or so compared to just getting it in there and cumming.

Also, I'm not sure if this is related in any way but, my penis sometimes.. how should I put it.. twitches when erect and when it does, i usually get that feeling you get right before cumming. It's usually after touching it even slightly sometimes, it'll twitch back towards me and the sensation of ejaculating follows. Though, I don't ejaculate unless I continue contact. If I just stop touching my penis, it'll go away.
I do have a tremor in my hands, and well I guess most of my body which means I shake all the time, mostly in my hands.. it's some kind of nerve disorder.. does anyone think it might be related?

Basically, my general problem here is when my penis gets erect, it's pretty much already at the state of ejaculation, and any form of touching, or contact with my penis will set me over the edge. Unless I just slightly touch it with my fingers on the shaft a little, then I can last about 20 mins of masturbating.. but if I grip. Forget it, I'm done after a jerk or two at that point, and if I'm having sex and haven't masturbated before hand, once I'm in, I'm done.
It's a very aggravating issue, and I'd like some opinions, maybe something I could try to help improve this?
