Did dinosaurs have penises

No. Only mammals have nipples.

==================================

No.

Animals that reproduce using eggs, either retained internally (oviparous) or laid externally (that is to say amphibians, reptiles and birds) feed their offspring using the yolks of their eggs.

However, mammals produce young that are fed on Mother's milk and the nipples are the tubes by which this milk is obtained by the young. Thus only mammals have nipples.

Dinosaurs are not mammals, they are reptiles and they laid eggs.
