ERB lived here in Pocatello, Idaho and began some of his best work here, writing as his stationery store failed (the site today is that of a taxi office and a parking lot). I can assure you that he lived and worked amidst the most genteel society, associating only with the best of the best (which at the time was very good indeed). One must assume that his environment and his milieu affected his writing, so I would say no, Tarzan was celibate until he met Jane and they were properly introduced (remember, Tarzan was in actuality an English Lord). After a suitable period of courtship and betrothal would come marriage and then certainly, Jane would "think of England" in their treetop cottage. But I am certain that Tarzan, being "Lord of the Apes", would never stoop to the "droit de Seigneur". To do so just wouldn't be, you know, British.
