what are possible causes of a dysfunction in the glans penis?

In my clinical practice as a psychiatrist, I realise that many male patients are concerned about their penis size. In sex therapy sessions, a lot of time is spent on providing correct information and sex education to the couple so as to dispel any myths related to sexuality and sexual behaviour. A common myth amongst males is that a large penis results in a female partner being orgasmic during intercourse. This is based on the mistaken belief that the vagina is the woman's major sex organ, whereas, in truth, the woman's most sensitive genital organ is her clitoris [1].

There are no known penis enlargement cream or pills that are scientifically proven to be effective. There are penile traction devices that have shown some potential in this area.
