Kindly suggest me the ways to cure premature ejaculation.

Hello doctor,

I am 25 years old, male. I have fast ejaculation. If I am very much sexually excited, ejaculation can happen also at about one minute. If I do sex second or third time in a row in this case duration of act can be four to six minutes or more, but in this case problem is that I sometimes lose erection during the act and I am much less excited, so I do not get big pleasure. I have some symptoms which, in my opinion, can have some connection with my problem of premature ejaculation: I started regular sexual life very late, at age 24, (one year ago) before it was not regular, but very rare. From the age of 13, I was making regular masturbation, almost every day, until I started regular sexual life (three to four times a week). (Now masturbation almost does not give me pleasure) .

I think that the head of my penis is too much sensitive, because it hurts me when it touches to my underwear, if the head of my penis is not completely covered by foreskin. From my childhood until the age of 14-15 the foreskin of my penis was narrow and I could not to make head of penis to come completely out of it. I noticed high sensitivity only after. Now it has no problem and it is very elastic. I am saying this last fact because maybe the sensitivity of my penis was because of later adaptation of penis head without cover. This period I have sex three to four times a week. During last one year the frequency of sexual acts was the same, but I want to have more often, minimum six days a week. Anyway, I am not sure this is the reason of my problem because also in the case if I do sex every day and next day I am very excited I will finish fast. With oral stimulation of my penis, it is very difficult for me finish, because it does not excite me very much and I need much more time to have ejaculation. My body temperature normally in the morning is about 97.88 degrees Fahrenheit, but at midday till evening it remains 98.6-99.0 degrees Fahrenheit Can it be the symptom of inflammation in my genitourinary system or somewhere else, or it is normal? (My general blood and urine analysis are perfect, everything is normal). What can I do for treatment of my problem?
