Do you maintain an erection after orgasm with intracavernosal alprostadil?

I climax so quickly and am checking into intrcavernosal alpostandil options like caverject or Edex. Has anyone used these and did you maintain an erection after orgasm?

Haven’t tried but doctor said it give erection for 1-2 hour even after orgasm

Nah no way once I blow I just creep down.

I tried caverject with varying results. Yes you can have an erection after ejaculation. The downside is that it can last awhile and you need something like sudafed, the allergy medicine, or go to the hospital if it lasts too long, which is possible.
