I overdosed on 22 g of pure amphetamine and ever since i can't ejaculate, it takes me ages and with a female i can go all night without ejaculating ?

Probably clopixel: Zuclopenthixol is a first generation antipsychotic of the thioxanthine( navane) class of antipsychotics developed by dr thomas ban on whose research unit i did an externship at central tennessee state hospital outside of nashville in 1980. Unfortunately, this drug can cause ejaculatory failure. I doubt it is from your overdose.
