Hi there can any one help me with this problem I can not get a very hard erection?

Erectile dysfunction. Erectile dysfunction is a common problem for men, becoming more common as they get older. Assuming there is not a hormonal, vascular or neurological problem that prevents erection, ED typically responds well to phosphodiesterase-5 inhibitors such as viagra (sildenafil) and Cialis (tadalafil). Some herbals have been used with mixed success.
