I Am 40 year old man & recently married. I am facing problem in sustaining erection. At times I do not get any erection or erection which ends before penetration. On these occasions I get a watery discharge from penis. When I get erection during foreplay I could not sustain it till penetration. Infact now a days its very rare for me to get a full hard erection. I am very disturbed due to this as it has been only 2 months since I got married. I never faced such problems earlier. I used to watch porn earlier and masturbate a lot. I had also used viagra for fun in past. Please tell me is this ED and what is the treatment. Please prescribe medicines.
