I have been using finasteride since I was 21, and I'm now 34. I understand some men feel this way, but it's anecdotal at best. Coupled with a hair transplant, I feel much better about myself and have a lot more sex than I used to.
As with most drugs both effectiveness and side-effects will vary.
Regardless, I’m happy for you and your sex life.
I made an assumption and which made me look like an ass...sorry about that.
