I was very greatful for the advice on this forum this morning. My boar Mario was acting scittish and when i picked him up I noticed he had a distended male part, it looked terribly painful but thanks to people sharing about this condition everything went back were it should be in an hr or so. I used a warm bath first, then coconut oil to help soften and miosturize the skin so his poor weenie could retract. I have had guinea pigs for thirty yrs and never had this happen. So glad to have this forum of caring moms and dads
