Can I Tell in Advance If I Am Going to Get Sexual Side Effects from Finasteride?

I am a 23 y.o male thinking about trying Fin. Actually, I am open to all options, be it Minoxidil or Keto shampoo or whatever. Currently, I think I should wait until the 14th to see the results of the Brotzu trial everyone is raving about. In the meantime, I want to speak with some doctors to see their perspective on the drug. So, is there any way of telling the likelihood of Fin side effects?  I read by some other posters on this subreddit that there is a 1 in 100,000 chance of ED. I was just wondering what your perspective might be?  What would the procedure be with ensuring the highest chance of keeping my dick if I chose to use Fin?  What about peppermint oil, rosemary oil, coconut oil, and other herbal remedies? Do you have any insight on these? Also, I just wanted to thank you for all your contributions to this subreddit. I have learned a great deal reading your comments.

There is no way to determine if you will get side effects, but people who are primed mentally are the ones that mostly get it. In reality, the risks are about 3%, and if you happen to be the 3%, there are ways to reduce the dose to address side effects that work in half of the men on the drug.  Remember, if you believe this will happen to you, it will happen to you. When my son went on it, he thought he was taking his daily vitamin P, he told me. His sex drive went down, so he called me and asked if that was a side effect. I told him it was for about 3% of people.
