HMMM, Idk if cialis or viagra will help you with your sex drive. It will help you get up and you can perform but your not going to be enjoying anything really. I guess I can't speak for how you will feel but it isn't natural and doesn't have the same feeling. I'm probably way older than you though. I would say if you want to help your sex drive quit using drugs lol. I have to be sober for like multiple months and then my drive comes back and im horny as fuck. Natural horniness is insane compared to like being on meth and cialis. I know you probably don't want to do that.
Running and like lifting weights daily helps alot with sex drive. I use to run like 3 miles a day and lift weights 4 to 5 times a week. It rebuilds dopamine and helps your brain. You can go slow if the running is wearing you out like run so slow it doesn't burn you out. I don't do this anymore obviously I do drugs everyday but just a thought I guess lol.
