Pinholes or cracks, these are not the defects associated with a synthetic condom. Whenever the condom fails, its failure is catastrophic and too obvious to ignore.
So are you say there is no risk?
If you penis head was covered, you've had no risk.
"You said if your penis head cover" I'm a woman so would it still be no risk once the penis head was cover?
If you had any penetration where your partner's penis head was not covered, you had a risk.
