No, cialis doesn't do that, unlike Viagra. Only problem im having is the morning woods last a bit longer for me.
Cialis can absolutely lead to priapism. According to the FDA adverse event reporting system (AERS) there were 93 cases of priapism in 2007: 74 for Viagra, 3 for Levitra, and 16 for Cialis. It's an uncommon side effect for sure but it is a possibility even with Cialis.
