I'm 29 next month. I don't know whether it's age, depression, anxiety or what, but it seems I'm having more and more difficultly staying hard. I can usually get it up and keep it up, so long as it's being stimulated. But as soon as it stops being stimulated it begins to shrivel. I would say within about 20 secs it begins to go down, and within about two minutes it's fully back to dangling status! Is this normal?
I have the same problem. Only with new/newer sexual partners though. Once I get used to them I can stay solid for hours. Anxiety i'm sure.
Hey man try a doctor. I know it's embarrassing, but we're talking about you sex life. That's like, your life at 29. You chose not to tell us anything about yourself other than age, so we can't be much help. One point you might consider - a big city offers sex therapists, male medicine doctors (primarily for gays, but very, very experienced and learned in everything about guys and sex - everything!) Country doctors would blush. But you gotta do something before it dangles irrevocably!
If you mean during masterbation, then it's not a problem, it's a common thing. You get hard during stimulation, when you stop, it starts to go back down as it's your mind really that triggers the erection. It's different when it's the girl in front of you that triggers it.
Better living through chemistry man. Tell the Dr. and he'll give you Viagra. It'll put it up and keep it up. Not taking any uppers are downers before sex are you? Sometime they can do that.
Try putting a constriction ring at the base of your penis. Not a metal one but one made of rubber. It will help keep the blood in your penis longer.
