Peyronie's disease is a possibility. An ultrasound would be a reasonable test to evaluate for this.
If present, there are various treatment options. Vitamin E supplementation and para-aminobenzoate tablets (B- complex substance) may be taken for several months. Chemical agents such as a calcium channel-blocker (e.g., verapamil), an enzyme that breaks down connective tissue (collagenase), and steroids (e.g., cortisone) may be injected into plaque or delivered by iontophoresis can all be considered.
Erectile dysfunction typically does not cause pain during erection. I would ensure there isn't any further disease present before attributing the symptoms to this.
I would consider a referral to a urologist.
Followup with your personal physician is essential.
