If that boy has STD
like Molluscum contagiosum
it is possible it can spread to your skin as well. Before writing this question I hope you have thoroughly washed your eyes in luke warm water as soon as he touched faeces in your eyes. Many diseases can spread to eyes causing inflammation and conjunctivitis
. Be careful next time. If any pain, burning sensation, watering of eyes, discharge from eyes, consult your Ophthalmologist.
