I keep breaking my frenulum and it keeps healing, freaking painful, lots of blood. Doctors say if it happens again I will have to get circumcised.
If that's the case you likely have an issue called frenulum breve and should consider medical treatment to correct it. it can manifest in mild to extreme forms, extreme being super restrictive and preventing the foreskin from sliding back at all, and mild resulting in frequent tear damage when the rest of the skin slides back freely but the frenulum bridge does not have the same elasticity.
You do NOT need full circumcision to correct this, the surgery to correct it is minor and involves simply removing the bridge, this will completely remove the problem.
I know this as Tamron has the same problem, and would often end up bleeding after sex, his surgery took 30 minutes and he was fully healed within a week.
