If you think you may want kids some day then i would freeze some sperm before you even start, once you have started its too late really as you would need a 3-6 month break (advice i was given by a sperm bank), as to erections well im on a fairly decent dose of pharmaceuticals as im in transition yet i can still get and maintain an erection if i wanted to, its mainly in the mind, with regard to caffeine and alcohol i would say just take it easy with them
