Hello,
Having frequent sex and doing it vigorously can make your penis sore and swell.
A prolonged erection can strain and sometimes injure the muscles and tissues.
Blood can also pool in the corpus cavernosa and
corpus spongiosum after a prolonged erection.
Suddenly thrusting your penis into your partner’s body at high speeds can also injure the tissue.
The things become worse when your partner is not properly lubricated.
For the time being, refrain from sexual activity, take
NSAID like
Advil for reducing pain and swelling and maintain hygiene.
If things do not improve, please see your clinician.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr AJEET SINGH, General & Family Physician
