Some may find it difficult to achieve an erection at all. The causes of erectile difficulties can be either psychological or physiological, with psychological causes thought to be most prevalent. The anxiety and pressure that a man might face as his body changes, may act as a catalyst for erectile difficulties. Achieving an erection becomes a process of prolonged stimulation and intimacy. It may take more vigorous manual or oral stimulation for men to get firm.
Some couples find it helpful to place the flaccid penis inside the vagina as a means of stimulation.
Experimenting with different forms of stimulation will increase sexual satisfaction while it helps the male to achieve an erection.
