We've had to dose our family with Combantrin due to pinworms. Everything I've read online says it's easy to reinfect oneself by touching or scratching the anus & then carrying the eggs to your mouth.
So, our concern is, how long should we wait to have sex, particularly oral sex?
Most sites say to re-dose everyone after 2 weeks to catch the next egg cycle,
But that doesn't really address specifically the sex question.
