Sorry didn’t address your question,
Viagra hits me in about 1 hour to 1.5 hours, since you never have done it before, it will probably hit you in 30 minutes.
Depends upon your age, remember it for us old farts, pushing 60.
Cialis is weird, takes at least 8 hours to get going, don’t know why, but then it stays for a couple of days.
If you’re on test, and have not had any sex for about 7 days, (no beating off either) the stuff is addictive.
