I've been having some trouble with my foreskin since I can't pull it back when my penis is erect, and it really hurts when I try. I'm wondering, could this be phimosis or maybe paraphimosis? Also, I'm curious if there's a way to treat this without surgery, or is surgery the way to go? If I do need surgery, is it safe to have it done at my age, and should I be worried about any side effects?

You may be experiencing phimosis, which is the inability to fully retract the foreskin over the head of the penis. This can cause pain and discomfort, especially during erections. Phimosis is different from paraphimosis, which is a medical emergency where the retracted foreskin cannot be returned to its original position. For phimosis treatment, you can try using topical steroid creams such as Betamethasone or Hydrocortisone. These creams can help to soften the foreskin and make it easier to retract. You can apply a pea-sized amount of the cream to the tight area twice a day for a few weeks. If conservative treatments do not work, then circumcision surgery may be recommended.
