I'm pretty worried because during sex I accidentally cut my frenulum and it bled quite a bit. The bleeding stopped after a while, but it's been a couple of days now, and I feel pain when my penis gets hard. It's strange because the pain comes and goes throughout the day, but there's none when I pee or otherwise. I read somewhere that I shouldn't panic and it might heal on its own in a few weeks, but I'd really like to know if there's any medication or treatment I could use to recover faster. Any advice would be really helpful.

Based on your description, it sounds like you have experienced a frenulum tear. To help with the pain and promote healing, you can take over-the-counter pain relievers such as ibuprofen. I recommend taking ibuprofen 400mg every 4-6 hours as needed for pain. Additionally, applying an antibiotic ointment like Neosporin to the affected area twice a day can help prevent infection and aid in healing. Make sure to keep the area clean and dry. In case of persistent or worsening symptoms, it is advisable to consult a healthcare professional for further evaluation and management.
