I guess, it depends on a person, but it works for me great!
Especially, with a glass of red wine.
Just figure out right dosage, start low, and progress up. You don't want to overdose it, believe me.
As for libido enhancement, I get better results taking Yohimbine orally than topically. Yes, I have tried both. Not saying topically doesn't do it at all, but I have seena greater effect orally. However, this is usually shunted due to the "ephedrine-dick" syndrome from the ECY stack I take.
