Kamagra Oral Jelly 100 mg is used to treat erectile dysfunction (impotence) in men, which is the inability to achieve or maintain a hard erect p*nis suitable for s*xual activity, due to insufficient blood flow to the p*nis. Kamagra Oral Jelly relaxes the blood vessels in the p*nis, increasing blood flow and causing an erection, which is the natural response to s*xual stimulation. However, Kamagra Oral Jelly will only work if you are s*xually aroused.
