Hello, i havr a problem of mastubation, i want to stop it and my erection is very weak and also have quick ejaculation.what medicine could i take please?

Find the cause first: To assess if one's erections have weakened, he should visit a primary doctor, who can check for possible causes: stress, depression, diabetes, high blood pressure, low testosterone, artery disease, high cholesterol, smoking, older age, etc... Causes found can be treated to help make erections stronger, firmer, longer lasting. A urologist can evaluate. Meds like viagra, cialis, or Levitra (vardenafil) may help.

Some ideas: Dr. Kwok has given you good advice. You won't be able to abstain from enjoying your body when you're alone, and this is something you should enjoy. For premature ejaculation when you're with your partner, learn the squeeze technique -- it's fun and you'll recondition yourself. If it's really erectile dysfunction, your physician can check you for prolactinoma and hemochromatosis.
