I've probably had hundreds of spermatophores ejaculate on my fingers and never felt a sting.
That's because you're a GUY, so you can't get impregnated!
And did you notice, this was COOKED squid? So, that's one more danger in eating cooked foods.
I'm wondering how long it'll take before squid sperm sac becomes a delicacy at San Francisco bay area sushi bars.
