Anybody with pharmacology knowledge know which medication would have less side effects in terms of libido and orgasm? prolactin?  

Haloperidol has a very strong binding affinity but is a inverse agonist as opposed to Risperidone which is antognist at the dopamine sites.

Is inverse agonsism better than straight up antagonism in the long term for your libido or if you want to take other medications that want to boost dopamine and bind to that same receptor? the pharmacology is so confusing for me and I don't know which medication would be better for me as PRN
