Men have such problems as mentioned by you in the query. Many times, the foreskin of an uncircumcised man gets stuck or does not retract to its original position. Normally they are caused by two conditions, 1) phimosis and 2) paraphimosis.
a) Phimosis: In this, you are not able to retract or pulled back the foreskin behind the head (glans) of the penis. Doctors explain that normally, every uncircumcised man can retract the foreskin of his penis by the age of 10 or 95% of boys can do it by the age of 17. The reason for it can be an infection, inflammation, or some other condition and if you are not able to retract it even after the year, you've got a problem and one need to visit a sexologist.
b) Paraphimosis: In this, One is able to pull back the foreskin of their penis but it gets trapped and then swollen behind the head or glans of the penis. It is considered an emergency as it leads to swelling and blockage of blood flow to the penis. Some of the symptoms and causes of paraphimosis are:
i) Pain in the glans or head of the penis due to swelling.
ii) Change in the colour of the penis i.e. it turns Red, white, blue, etc due to low or poor blood flow to the penis.
iii) An improperly circumcised penis.
iv) Strong or repetitive sexual practices including sex, masturbation, etc.
v) Infection, poor hygiene, prolonged foreskin retraction and previous foreskin injury
As per your information and inputs, I understand that you have got the second type of foreskin problem. In order to give relief to some extent, you can try the following:
a) Apply ice to the penis to reduce swelling and try to retract the foreskin back to its normal position.
b) Apply soapy water or soap to the head or glans of the penis and try to retract the foreskin back to its normal position.
c) Apply some natural oil like coconut oil or lubricants like vaseline on penis to lubricate the foreskin and try to bring back the skin to its original position.
d) You can even visit a pharmacist and try corticosteroid cream or ointment like hydrocortisone. Apply it two or three times a day. Apply it on the inside, outside to tip of the foreskin so as to retrieve it to its original place. Do consult the pharmacist before getting the over-the-counter treatment.
Even after doing the above steps, you are not able to retract your foreskin to its original position and you are still having swelling or pain at the tip, do visit a sexologist who would help you with the best medication after thorough examination and tests.
Do remember that once your symptoms fade away or you are able to retract back the foreskin, always clean the penis daily with lukewarm water using mild soap. While cleaning, do retract the foreskin and clean. avoid using soap, shampoo, deodorant and talcum powder and after washing or shower dry it gently with a clean napkin or towel and after peeing do shake off the remaining or excess urine.
Note: Anything in excess is harmful and you mentioned about 3-4 times sex within a span of 4 hours is actually vigorous and excess. Do enjoy sex regularly but refrain from excess as it can harm you and your sex life after a certain period.
