Perhaps you've experienced it once, while having sex it's not possible to get a hard penis, or it becomes flaccid during the deed.
The good news is that erectile dysfunction problems can often be treated. If fact, you often have this matter in your own hands.
The vast majority of men regularly gets an erection. Their penis becomes hard at night one or multiple times. Also, some men wake up with an erection in the morning.
An erection pill works best on an empty stomach. Don't take it after you had a big meal. This will slow down the absorption process of the pill.
Even the best sex partner doesn't always manage to perform well in bed. Almost every man has had a moment of failure to get an erection.
