I started 10 years ago with Viagra, migrated to 10 mg Cialis, then a few years ago, upgraded to 20 mg Cialis. Doc asked me to try Stendra, but that didn’t work well for me. So, I’m currently using the 20 mg Cialis which works well. Biggest problem for me is the stuffy nose. Hard to breath when I’m performing cunnilingus. That and the flushed face, but no one is taking pics and the lights are usually low so that’s not much of problem.
