^^sexual desire is related to dopamine, this is true but there are other parts of the equation that havent been figured out yet imo..sadly, most drugs that boost dopamine also increase anxiety and cause other problems..
the only thing i have taken that is legal and OTC that has increased sex drive is yohimbe..problem is, it only seemed to work half of the time and it definitely increased my anxiety and blood pressure..sadly there just arent any truly effective sexual enhancers out there OTC..
