1. Maybe yes, maybe no. But definitely not tip-top fit condition where I can just go and run a 42km marathon
2. As long as i'm still stroking it, it will stay hard until it comes. But I'm not exactly sure if it's 100% erected/hard. But once I stop watching and stop touching it, it will not stay erect for long.
3. I think the 3rd one could be one of the reason and I have no idea how to get rid of that nervous feeling.

just relax, be confident, and most of all, dont stress out your little bro down there.

well, it's not i can't get it up
the problem lies in maintaining it or keeping it rock hard for a certain amount of time
sometimes halfway through, it will soften a lil and i realize my other body parts (eg abdomen) will get tired and eventually it will just fail on me

i wanted to try medication, but i suppose i am too young for it and it's not good to rely on it

slap her and tell her you're the boss
joking.

yes psychological factors could play a part. couple that with certain physiological factors and it gets hard, no pun intended.
on a serious note, i really do know a urologist, whom we have not seen for a while but was a good friend.
he has been practicing and specialising for a long time and he works around the klang valley.

Stress can take effect at any time. Before and also during erection.

Better to seek medical advice.

would u mind sharing his contact n working place?
i was thinking of quitting porn and fapping for a while...not sure how much it will help

You can overload your mind with porn so much that ordinary sexual encounters will not give you the desired Stimulus. Your expectations may be a bit too high and it will affect your "performance". Lay off the porn.

I'm having a problem maintaining my erection and sometimes I can't get it up before sex. Is it possible that I'm suffering from erectile dysfunction? I admit sometimes I get really nervous and that fellar below refuse to cooperate before sex. Could it be sexual performance anxiety? Meanwhile I suspect it could be due to poor blood circulation but how do I verify that. One of my problem is I always have cold hands and when I get nervous i'll have cold sweat. Please advice. I do not want to rely on drugs like <removed> or <removed>.

I'm only 24 years old and she is the first girl I'm havin sex with. Whenever I lose erection, she gets really frustrated and a lot of times she just want me to come and then go to sleep. I don't want this ED issue to affect our relationship. If I were to see an urologist, how much does it usually cost? Please shed some light on this issue.
